I have a DataGrid populated via an Array. The last column in the DataGrid uses an ItemRenderer (Button). I want to show the Button in certain rows but not in others (leave those empty). I've looked everywhere for an example or even a clue how to do this (tried labelFunction on DG, etc.) but can't find anything about it. Any help would be appreciated. Thanks!
Okay... with (lots of) help, figured it out.
First off, I'm not sure why the itemRenderer requires a container but it does. The array must also be checked from the itemRenderer and not from the main application... again, I don't know why since the debugger shows it going through the exact same loop/events, etc.).
If interested here's the relevant parts of the code:
Main App:---
{col1:'', col2:'', col3:'', col4:'', col5:'', col6:'', col7: '', col8:'', col9:'', col10:'', col11:'yo'}];
public function initData():void
{ xferSchedule.dataProvider = schedArray; }
]]>
an item renderer does not have to be a container, it has to implement IDataRenderer (a Button does not). One could extend Button and implement this interface to get a simple button renderer. If you want it to display conditionally, you will accomplish this by handling those conditions within the renderer based on the data.
Now this might get slightly complex. I would recommend you to define you an XML instead of Array of Objects. If the node has the type property button, then it would create button at that cell whose value type is button.
How to create a button dynamically inside a grid which is yet again dynamic?
This might end into the whole component being dynamic.

I'm wondering if anyone has come across this issue.
I have two radio buttons on a canvas app that I am attempting to control the values displayed within a list box.
RadioButtons.Items: ["SomeValueA","SomeValueB"]
The list box control should be getting reset whenever the value of the radio button changes.
UpdateContext({resetList: !resetList});
UpdateContext({resetList: !resetList});
Reset(lbListbox);
lbListbox.Reset: resetList
For the list box itself I have the following for Items:
Switch(
RadioButtons.Selected.Value,
"SomeValueA",
Sort(
EntityA.FieldName,
Descending
),
"SomeValueB",
Sort(
EntityB.'Some other field name',
Descending
)
)
The problem is when I select 'SomeValueA' the list box properly populates with the values from EntityA.FieldName but when I then select 'SomeValueB' from the radio buttons the list box blanks out with empty records. There appears to be items in the list box that I can scroll through and select but not see.
If I put two list boxes on the screen and set their Items event to the specific entity the values show up properly in both list boxes so I know the entity naming/field is correct.
I've tried it without the reset of the list box, I've tried it using collections made out of the entity records.
Has anyone come across this who maybe has a solution. I was going to try to put two list boxes on top of one another and either hide/show or bring to front the active list but that also doesn't want to work.
thanks!
(Received this post from another source, figured I might as well post back here as well)
Got this to work, but it was a bit finicky. The catch seemed to be giving the List a value-pairing table, instead of just a list of values.
First I collected the Option Sets from CDS, and added a column to indicate the source name, for reference. This could easily be combined into a single collection, and then filtered later but I was thinking simple.
ClearCollect(colOptionSet1,AddColumns(Choices('Ownership (Accounts)'),"appSource","Ownership"));
ClearCollect(colOptionSet2,AddColumns(Choices('Preferred Method of Contact (Accounts)'),"appSource","Preferred Method"));
Next added a Radio button identical to yours.
Then added a List control with Items equal to
If( Radio1.Selected.Value = "SomeValueA", colOptionSet1, Radio1.Selected.Value = "SomeValueB", colOptionSet2 )
You may need to use the right-side property pane to toggle between Value and "appSource" (from collections above), but this did allow me to toggle between two separate Option Set fields in a single list.
Patching/writing this back is gonna be another hurdle. 😝
I've really strange behavior and I spent a couple of days to try to figure out what is a problem.
MooTools methods makes my input fields not clickable, and I don't know why.
$$('.class1.class2').makeResizable({
});
Above piece of code needs to make all children of div which has class 'class1' & 'class2' to be re-sizable, and that works perfectly but beside that it also makes input fields not clickable.
Does anybody had the similar problem?
Any kind of help will be appreciate.
Thanks
so the problem is that you have no handle passed in. when you fail to do that, the whole element becomes a listener for mousedown and attempts to click into any child element will not bubble correctly, resulting in weird behaviour.
I also found a bug in the logic for adding handlers, which seems to not evaluate handles correctly
https://github.com/mootools/mootools-more/blob/master/Source/Drag/Drag.js#L66 is wrong on many levels - it expects a collection / array of elements but looks in the global document and not child elements - yet it ends up picking element anyway and ignores passed collections like $$('.class1 .resizer')
i did a small change to accept a string for a child selector and added a resize handler.
http://jsfiddle.net/pbu5uzho/
you should submit this bug to https://github.com/mootools/mootools-more/issues though i doubt it will get picked up.
$$('.class1').makeResizable({
handle: '.resizer'
});
the change I did to make this work was:
this.handles = this.element.getElements(this.options.handle);
alternatively, you can use something like InteractJS to handle this.
I'm not 100% sure but can you try this one
I think you are missing (,)
$$('.class1,.class2').makeResizable({
});
I need to use checkbox as radiobutton.
In my case I'd like to define a checkbox group but I don't know why.
If I select one checkbox, I'd like that other checkbox are deselecting
Could you help me ?
Thanks
If there is a static amount of radio buttons you need, you could use Spark States.
<s:states>
<s:State name="check1"/>
<s:Stage name="check2"/>
</s:States>
<s:CheckBox selected="false" selected.check1="true" click="currentState='check1'"/>
<s:CheckBox selected="false" selected.check2="true" click="currentState='check2'"/>
When you click the first one, it triggers the "check1" state in which the first check box is selected and the other is unselected. Clicking the second one does the opposite. Obviously, this is not as flexible as some would hope. But if it's for an interface element (such as an options menu), it's perfect.
States are incredibly useful if you understand how and when to use them. This past weekend, I created an all-Flex slideshow using them and it is a great example of how powerful that simple little array can be.
EDIT: I just threw together a simple app to test this, and it doesn't look like it will work using click. I'm sure you could tinker with another event to get it to work, though. Sorry this didn't work.
I'd use RadioButtons, but if you really wanted to do it, I'd take LondonDrugs_MediaServices approach.
CheckBox and RadioButton both extend from ToggleButtonBase.
Create your own CheckBoxRadioButtonSkin. Copy the CheckBoxSkin to it and rename the hostComponent.
Then use this skin on your radioButton to make it appear to be checkbox.
I have had a requirement like this before and I used a Datagrid with Checkbox inside as itemRenderer.
I subclassed the Checkbox, overrode data getter so that each time it is clicked all the items of Datagrid are unselected, unchecked except for him. This method acquired some advantages:
Flexible to add number of options programmaticcally.
Display title of option group or not.
Enable to use scrollbar if there is a limit of space.
Hope the solution is what you are looking for.
Hopefully a quick question here. I have setup a "LayoutPage" custom class (based on MovieClip) and I am attemptimg to create a "selected" behaviour.
When I assign my "addEventListener(MouseEvent.CLICK,toggleSelection)" from within my custom class, everything works as expected, clicking any object of that class does display the correct behaviour.
Now, I would like to extend the functionality by adding keyboard modifyer to either extend the selection or replace it.
For this, I thought of moving the "addEventListener" out of the class and put it inside the parent instead (my "PageLayout" class where all the "LayoutPage" live). But by doing so, the click event no longer register on the "LayoutPage" class but rather on its individual children (Page icon, Page number text field, Page Highlight shape, etc.)
Can anybody explain why this is happening and how I can circumvent it?
TIA
This should be happening no matter where you put your addEventListener. It is because mouseChildren is switched on by default. It is probably best to turn it off inside your LayoutPage class like so:
myLayoutPage.mouseChildren = false;
The actual issue is that use are probably using currentTarget to reference the item that was clicked on in your event handler method. Take a look at the descriptions for currentTarget and target to get a good idea of how they differ.
A good option would be to add your listener at the PageLayout level, but add it specifically to each LayoutPage child like so:
myLayoutPage.addEventListener(MouseEvent.CLICK, toggleSelection);
This way you can just use target in your handlers. But it would probably be best to still switch mouseChildren to false on each of your LayoutPage instances.
I'd like to conditionally hide a tab in a TabNavigator. It seems that setting visible doesn't work properly (presumably because this is how the TabNavigator hides the tabs that aren't currently selected).
What's the right way to do this?
You can do this by making use of TabNavigator's getTabAt() method which returns the Button that makes up the visual tab. You can then set that Button's visible property. It's a little tricky to get this setup with a bindings, but it's doable.
You could also consider just disabling the tab instead, which you can do by setting enabled on the corresponding TabNavigator child (for which visible didn't work).
What do you mean by hide? If you actually mean remove, then just take your array that's bound to the data in the TabNavigator, and remove the applicable element from it.
If you want to just have them removed temporarily, create a component of your own that encapsulates the TabNavigator and has an array of removed tabs and an array of actual tabs. Then handle this as you see fit.
You might want to check out the flexlib project. They have a component called SuperTabNavigator that adds a lot of functionality to the base Flex TabNavigator, including hiding tabs (I think).
If you do have to create your own component, though, it's a bit more tricky. The thing to know is that "tabs" are actually specially styled buttons, contained within a TabBar component (the TabBar is then contained within the TabNavigator). What you'll have to do then, is subclass TabNavigator and have some property on your views (i.e. the canvases, etc. that are added to the TabNavigator) that is bound to the visible and includeInLayout properties of the TabBar buttons.
In essence, what you'll have is something like:
BindingUtils.bindProperty( tabButton, "visible", view, "someProperty" );
BindingUtils.bindProperty( tabButton, "includeInLayout", view, "someProperty" );
I don't know about TabNavigator, but in other containers, you can set the includeInLayout property to false and it will be ignored. You probably still need to combine it with visible.
var secondTab = tabNavigator.removeChildAt(0);
