MvxTabsFragmentActivity - Remove tabs - mvvmcross

Is there any way to remove tabs from an MvxTabsFragmentActivity-inherited class? I mean, currently there's only AddTab<T>() method for adding tabs. But, what if I want to remove tabs?
TIA,
Pap

No - MvxTabsFragmentActivity doesn't provide any RemoveTab functionality currently.
The source for this activity is https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross.Droid.Fragging/MvxTabsFragmentActivity.cs - you should be able to use this as a starting point for your own needs.

UPDATE:
After following #Stuart's advice and-as I mentioned in my comment below-I added the source code for the MvxTabsFragmentActivity class to my project and added the following method-to remove all tabs-which was all I wanted:
public void RemoveAllTabs()
{
// First, detach the curent tab using SupportFragmentManager object.
if (_currentTab != null)
{
var tag = _currentTab.CachedFragment.Tag;
_currentTab.CachedFragment = SupportFragmentManager.FindFragmentByTag( tag );
if (_currentTab.CachedFragment != null && !_currentTab.CachedFragment.IsDetached)
{
var ft = SupportFragmentManager.BeginTransaction();
ft.Detach( _currentTab.CachedFragment );
ft.Commit();
SupportFragmentManager.ExecutePendingTransactions();
}
}
// Second remove all tabs from TabHost object
if (_tabHost != null)
_tabHost.ClearAllTabs();
// And lastly, empty our _lookup table(actually a Dictionary).
_lookup.Clear();
_currentTab = null; // Clear the current tab
}
I guess if someone wanted to have a specific tab removed he could use the SupportFragmentManager object and have something like this:
public void RemoveTab( string tag )
{
var fragment = SupportFragmentManager.FindFragmentByTag( tag );
if (fragment != null && ! fragment.IsDetached)
{
var ft = SupportFragmentManager.BeginTransaction();
ft.Detach( fragment );
ft.Commit();
SupportFragmentManager.ExecutePendingTransactions();
//_tabHost.TabWidget.RemoveView( fragment.View ); // Neither this..
//_tabHost.RemoveView( fragment.View ); // .. or this removed the tab from the Tabhost.
}
}
However, although the above code was successful at removing the fragment/view inside the tab, the tab itself remained-showing a blank/empty tab. I couldn't find a TabHost.RemoveTab() or TabHost.TabWidget.RemoveTab() methods and the TabHost.RemoveView()/TabHost.TabWidget.RemoveView() did not work.
Notes: I renamed the MvxTabsFragmentActivity to something else and included all copyright notices at the top of the class in my project. Thanks again to #Stuart.

Cannot remove default buttons from autodesk-forge viewer panel (Autodesk.Viewing.Private.GuiViewer3D)

I would like to remove measure, text format and properties buttons. See image.
I can only remove "toolbar-settingsTool" but not able remove above three buttons.
onExtensionLoaded = (e) => {
if (e.extensionId === 'Autodesk.DefaultTools.NavTools') {
// Remove settings tools
const settingsTools = viewer.toolbar.getControl('settingsTools');
settingsTools.removeControl('toolbar-settingsTool');
//settingsTools.removeControl('toolbar-fullscreenTool');
// Remove settings tools
const navTools = viewer.toolbar.getControl('navTools');
navTools.removeControl('toolbar-propertiesTool');
// Remove model tools
const modelTools = viewer.toolbar.getControl('modelTools');
modelTools.removeControl('toolbar-modelStructureTool');
}
}
viewer.addEventListener(
Autodesk.Viewing.EXTENSION_LOADED_EVENT,
this.onExtensionLoaded);
Can you please help me? Thank you.

Here is my code.
Some toolbars are initialized when loading the corresponding extension such as measurement ('Autodesk.Measure'). If you still need to use these functionalities in the workflow, yet only need to put the button to your own toolbars, or no button, you will need to check the corresponding extension if it supports removing the button only. e.g. in 'Autodesk.Measure' extension, it has the method measurementToolbarButton.removeFromParent, by which, the default button will be removed, while the functionalities of measurement still exists. The code could be:
ext = NOP_VIEWER.getExtension('Autodesk.Measure')
ext.measurementToolbarButton.removeFromParent()
When you need to switch to measure mode by your own button, call the method below:
NOP_VIEWER.setActiveNavigationTool('measure')
If you do not need the functionalities at all, just unload the extension. The default button will also be removed.
Thank you Xiaodong Liang. That works. I was able to remove measure and properties icons using following code:
onExtensionLoaded = (e) => {
// Remove "Settings" icon
if (e.extensionId === 'Autodesk.DefaultTools.NavTools') {
// Remove settings tools
const settingsTools = viewer.toolbar.getControl('settingsTools');
settingsTools.removeControl('toolbar-settingsTool');
//settingsTools.removeControl('toolbar-fullscreenTool');
}
// Remove measurement icon
else if (e.extensionId === 'Autodesk.Measure') {
var ext = viewer.getExtension('Autodesk.Measure');
ext.measurementToolbarButton.removeFromParent();
}
// Remove "Text" icon
else if (e.extensionId === 'Autodesk.Hyperlink') {
var ext = viewer.getExtension('Autodesk.Hyperlink');
ext.tool.removeFromParent();
}
// Remove properties icon
else if (e.extensionId === 'Autodesk.PropertiesManager') {
var ext = viewer.getExtension('Autodesk.PropertiesManager');
ext._toolbarButton.removeFromParent();
}
}
Is there any way to remove "Select Text" (T) icon? Following code is not working:
var ext = viewer.getExtension('Autodesk.Hyperlink');
ext.tool.removeFromParent();
Thank you.

Flex 4 TextArea: automatic character escaping in HTML/TextFlow links

I'm using the Spark's TextArea that contains links like this:
#hashtag
As you can see, this is a link to the Twitter search page for the specific hashtag. The hash-sign must be escaped in the query string. But, I have a problem here: when I click the link, the '%' symbol gets escaped automatically and the URL becomes corrupted (...search?q=%2523hashtag). Can I turn off this automatic escaping?
The '#' sign, if used in the URL, does not become escaped, and therefore the Twitter page does not open correctly in this case. So I cannot use neither '#' nor '%23' in the URL.
I would appreciate any solution for this.
Thank you.
Ok... so far, I couldn't find a way to turn off the automatic escaping of the URL when it's clicked. But I've found the workaround instead.
Basically, I add a custom click handler to all the link elements inside the TextFlow and open the links manually when clicked (instead of a built-in TLF behavior). Like this:
public function addLinkHandler( textFlowOrGroupElement: FlowGroupElement ): void
{
// scan the flow elements
for ( var f1: int = 0; f1 < textFlowOrGroupElement.numChildren; f1 ++ ) {
// found element
var curFlowGroupElement: FlowElement = textFlowOrGroupElement.getChildAt( f1 );
// if this is the link element, add the click event listener
if ( curFlowGroupElement is LinkElement ) {
( curFlowGroupElement as LinkElement ).addEventListener( FlowElementMouseEvent.CLICK, onLinkClick );
}
// if this is another flow group
else if ( curFlowGroupElement is FlowGroupElement ) {
// scan this group in turn, recursively
addLinkHandler( curFlowGroupElement as FlowGroupElement );
}
}
}
and here is the click handler for the links:
public function onLinkClick( e: FlowElementMouseEvent ): void
{
e.stopImmediatePropagation();
e.preventDefault();
var linkElement: LinkElement = e.flowElement as LinkElement;
navigateToURL( new URLRequest( linkElement.href ), '_blank' );
}
So in the end to make the Twitter-hashtag links work correctly in the TextArea, I do this:
addLinkHandler( textArea.textFlow );
P.S. The algorithm of adding the click handlers is based on this post, but optimized.

Tooltip on advanced datagrid column in Flex

I have a advanced data grid with columns as status, enabled, owner, name.
I will get data for status as 'applicable' or 'success' or 'failure' .
When the status is coming as 'applicable', i have to show the tool tip when move the mouse over there. Can you please help me out how to do it?
You need to create a GridItemRenderer and here is some sample code to put within the script block of your custom GridItemRenderer:
import mx.controls.ToolTip;
import mx.core.IUIComponent;
import mx.managers.ToolTipManager;
public var applicableToolTip:ToolTip;
private function createToolTip(event:Event):void {
if (data["status"] == "applicable") {
var stagePoint:Point = event.target.localToGlobal(new Point(event.target.x, event.target.y));
applicableToolTip = ToolTipManager.createToolTip(
"Your applicable message here",
stagePoint.x,
stagePoint.y,
null,
IUIComponent(event.currentTarget)
) as ToolTip;
}
}
private function destroyToolTip(event : Event) : void {
if (applicableToolTip != null)
ToolTipManager.destroyToolTip(applicableToolTip);
}
Then in the label field within the renderer add the attributes rollOver="createToolTip(event)" and rollOut="destroyToolTip(event)"
If a TooTip Manager is not needed then you can have a dataTip function which constructs the message and set displayToolTip property of column to true.
If your tooltip is inside your xml data you can specify dataTipField on DataGridColumn.
For example:
var col:DataGridColumn = new DataGridColumn();
col.dataTipField = "#statusTooltip";
col.showDataTips = true;
if your xml item looks something like:
<item id="..." status="applicable" statusTooltip="My tootlip text"/>

Magento: Disable module for any particular store

Suppose, I have 3 stores.
I want to disable a module in Store 2. I only want it to be enabled in Store 1 and Store 3.
I see that I can do it by:-
Going to System -> Configuration -> Advanced
Selecting desired store from Current Configuration Scope dropdown list.
But this does not work fully.
And, I also don't want to check store in the module code itself or create system configuration field for the module to check/uncheck store to enable/disable.
What I am expecting is by adding some code in app/etc/modules/MyNamespace_MyModule.xml. Can we do it this way?
To disable a module on the store scope, I've found it's possible to do it like this:
Move app/code/core/Mage/Core/Model/Config.php to app/code/local/Mage/Core/Model/Config.php
Inside Config.php find the method "loadModulesConfiguration" Don't change anything, but add the following code to make the method look like this.
public function loadModulesConfiguration($fileName, $mergeToObject = null, $mergeModel=null)
{
$disableLocalModules = !$this->_canUseLocalModules();
if ($mergeToObject === null) {
$mergeToObject = clone $this->_prototype;
$mergeToObject->loadString('<config/>');
}
if ($mergeModel === null) {
$mergeModel = clone $this->_prototype;
}
$modules = $this->getNode('modules')->children();
foreach ($modules as $modName=>$module) {
if ($module->is('active')) {
// Begin additional code
if((bool)$module->restricted) {
$restricted = explode(',', (string)$module->restricted);
$runCode = (isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : 'default');
if(in_array($runCode, $restricted)) {
continue;
}
}
// End additional code
if ($disableLocalModules && ('local' === (string)$module->codePool)) {
continue;
}
if (!is_array($fileName)) {
$fileName = array($fileName);
}
foreach ($fileName as $configFile) {
$configFile = $this->getModuleDir('etc', $modName).DS.$configFile;
if ($mergeModel->loadFile($configFile)) {
$mergeToObject->extend($mergeModel, true);
}
}
}
}
return $mergeToObject;
}
The new code will cause the method to also check for a new node in the module xml file, <restricted>. If the node exists, the value would be a comma separated list of store codes that you do NOT want the module to load on. If you have multiple stores, the $_SERVER variable "MAGE_RUN_CODE" should be set with the current store code. If it's not set, the script will fallback to assuming the store code is "default" which is what it is by default unless for some bizarre reason you decide to change that in the backend.
A modules xml file could then look like this:
<?xml version="1.0"?>
<config>
<modules>
<MyPackage_MyModule>
<active>false</active>
<restricted>mystore1,mystore4,mystore5</restricted>
<codePool>local</codePool>
</MyPackage_MyModule>
</modules>
</config>
With this, the module will not even load while on the stores with a store code of mystore1, mystore4, or mystore5. The <restricted> tag is entirely optional, if you omit it the module will load as it normally would.
This configuration just disables module output in layout for frontend, but module controllers, event observers, admin pages, etc still working.
Also don't forget to specify your module name in layout files definition, otherwise all the layout file content will be loaded for a particular store:
<config>
<layout>
<module_alias module="Module_Name">
<file>yourlayoutfile.xml</file>
</module_alias>
</layout>
</config>
If you are developing a module and want to disable full its functionality on the frontent for a particular store, then you should create a configuration field of "Yes/No" type and check its value via Mage::getStoreConfigFlag('config/field/path') in your module code.
I was using Eric solution for a while. In my case I disabled certain module responsible for Layered Navigation in one of my shops - thus returning to default Layered Navigation behaviour.
And it looked like its working, but after a while I've noticed that layered navigation options stopped to appear where they should. Soon I've noticed that in fact the module that should not work on this shop continued to work. Then I realized that when I disable configuration cache Eric's solution works, but after enabling it again it stops.
After a while I realized it had to work that way, with configuration cache enabled, because Eric's solution includes (or not) specified config files in global xml only while this xml is being generated. Then its cached and called from cache only. So when it was generated from site which should use some module it was included, and then used also on site which wasn't suppose to use it.
Anyway I worked out another solution, based on Eric's code (using restricted in modules config). I thought Magento should decide what to load when class is being requested. Then it could check what is current MAGE_RUN_CODE and use it dynamically.
There is a method in Mage_Core_Model_Config which is responsible for getting class name: getGroupedClassName.
Here is the code I used there:
if (strpos($className, 'Pneumatig_') !== false) {
$var = substr($className, 0, strpos($className, '_', strpos($className, '_') + 1));
if (isset($this->_xml->modules->$var)) {
if ((bool)$this->_xml->modules->$var->restricted === true) {
$code = isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : 'default';
if (strpos((string)$this->_xml->modules->$var->restricted, $code) !== false) {
$className = '';
}
}
}
}
This Pneumatig condition is because all my modules start from Company name, so i wanted to avoid not necessary processing, but its optional, code should work without it, or you can change it to anything else.
Then I get actual module name [Company]_[Module], and then check if its enabled in _xml (which is current configuration object). If it is restricted I clear $className so it force Magento to load the default in next line.
And this code is added just before is empty condition:
// Second - if entity is not rewritten then use class prefix to form class name
if (empty($className)) {
if (!empty($config)) {
$className = $config->getClassName();
}
if (empty($className)) {
$className = 'mage_'.$group.'_'.$groupType;
}
if (!empty($class)) {
$className .= '_'.$class;
}
$className = uc_words($className);
}
$this->_classNameCache[$groupRootNode][$group][$class] = $className;
return $className;
And for your convenience i paste whole getGroupedClassName code:
public function getGroupedClassName($groupType, $classId, $groupRootNode=null)
{
if (empty($groupRootNode)) {
$groupRootNode = 'global/'.$groupType.'s';
}
$classArr = explode('/', trim($classId));
$group = $classArr[0];
$class = !empty($classArr[1]) ? $classArr[1] : null;
if (isset($this->_classNameCache[$groupRootNode][$group][$class])) {
return $this->_classNameCache[$groupRootNode][$group][$class];
}
$config = $this->_xml->global->{$groupType.'s'}->{$group};
// First - check maybe the entity class was rewritten
$className = null;
if (isset($config->rewrite->$class)) {
$className = (string)$config->rewrite->$class;
} else {
/**
* Backwards compatibility for pre-MMDB extensions.
* In MMDB release resource nodes <..._mysql4> were renamed to <..._resource>. So <deprecatedNode> is left
* to keep name of previously used nodes, that still may be used by non-updated extensions.
*/
if (isset($config->deprecatedNode)) {
$deprecatedNode = $config->deprecatedNode;
$configOld = $this->_xml->global->{$groupType.'s'}->$deprecatedNode;
if (isset($configOld->rewrite->$class)) {
$className = (string) $configOld->rewrite->$class;
}
}
}
//START CHECKING IF CLASS MODULE IS ENABLED
if (strpos($className, 'Pneumatig_') !== false) {
$var = substr($className, 0, strpos($className, '_', strpos($className, '_') + 1));
if (isset($this->_xml->modules->$var)) {
if ((bool)$this->_xml->modules->$var->restricted === true) {
$code = isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : 'default';
if (strpos((string)$this->_xml->modules->$var->restricted, $code) !== false) {
$className = '';
}
}
}
}
//END CHECKING IF CLASS MODULE IS ENABLED
// Second - if entity is not rewritten then use class prefix to form class name
if (empty($className)) {
if (!empty($config)) {
$className = $config->getClassName();
}
if (empty($className)) {
$className = 'mage_'.$group.'_'.$groupType;
}
if (!empty($class)) {
$className .= '_'.$class;
}
$className = uc_words($className);
}
$this->_classNameCache[$groupRootNode][$group][$class] = $className;
return $className;
}
My clients install of Magento 1.8.1.0 has a problematic module that breaks another site's menu on a multi-store setup. The solution above posted by Eric Hainer didn't work for this install, so I altered it slightly:
Instead of using $_SERVER['MAGE_RUN_CODE'], I used $_SERVER['SERVER_NAME']. Worked like a charm. :)
So instead of:
$runCode = (isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : 'default');
use:
$runCode = (isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'] : 'www.site1.com');
and instead of:
<restricted>mystore1,mystore4,mystore5</restricted>
use:
<restricted>www.site2.com,www.site3.com</restricted>
obviously changing "www.site1.com", "www.site2.com", and "www.site3.com" with your own locations.
Thanks for the idea Eric :)

MediaWiki Extension question / suggestion

Complete beginner here. I want to create a new tab on each page that has a custom action. When clicked, it takes you to a new page which has custom HTML on it along with the text or the original article.
So far I could create a new Tab and could give a custom action mycustomaction to it. I am pasting what I did so far here. Please let me know if I am using the correct hooks etc. and what is a better way to achieve this basic functionality.
So far with their docs I have done this:
#Hook for Tab
$wgHooks['SkinTemplateContentActions'][] = 'myTab';
#Callback
function myTab( $content_actions) {
global $wgTitle;
$content_actions['0'] = array(
'text' => 'my custom label',
'href' => $wgTitle->getFullURL( 'action=mycustomaction' ),
);
return true;
}
#new action hook
$wgHooks['UnknownAction'][] = 'mycustomaction';
#callback
function mycustomaction($action, $article) {
echo $action;
return true;
}
This gives me error:
No such action
The action specified by the URL is invalid. You might have mistyped the URL, or followed an incorrect link. This might also indicate a bug in the software used by yourplugin
What I was doing wrong:
$content_actions[‘0’] should simply be $content_actions[] (minor nitpick)
$content_actions is passed-by-reference, it should be function myTab( &$content_actions ) {}
mycustomaction() should do something along the lines of
if ( $action == ‘mycustomaction’ ) {
do stuff; return false;
}
else {
return true;
}
It should use $wgOut->addHTML() instead of echo
Thanks a lot everyone for your help!
