I am writing a simple plugin that changes the whole content of a Sublime editor and replaces it with something else. When doing this
viewRegion = sublime.Region(0, self.view.size())
everything = self.view.substr(viewRegion)
self.view.replace(edit, viewRegion, everything)
the view scrolls to the top. How do I prevent this or restore the original viewport?
It turns out, there isn't really a good way. You can try to get around the replace as much as possible (e.g. by using the excellent merge_utils), but this will always change the position after the command is finished.
As a hack, you can save the position and restore it in a timeout like this:
def format(self, edit):
self.curpos = self.view.viewport_position()
self.selection = self.view.sel()[0]
viewRegion = sublime.Region(0, self.view.size())
everything = self.view.substr(viewRegion)
# do something useful
self.view.replace(edit, viewRegion, everything)
# reestablish selection
sublime.set_timeout(self.reset_pos, 0)
def reset_pos(self):
self.view.sel().clear()
self.view.sel().add(self.selection)
self.view.set_viewport_position(self.curpos, False)

I have Matlab 2019b, GUI Layout Toolbox 2.3.4 and t all runs on MacOs 14 Mojave.
I want to create button in in a UI that have icons/images instead of text. I have seen here:
https://undocumentedmatlab.com/blog/html-support-in-matlab-uicomponents/
that it is supposed to be possible to use HTML to render the button contents.
So - I try this sample code:
figure('MenuBar','none','Name','GUI-TEST','NumberTitle','off','Position',[200,200,140,90]);
push_btn = uicontrol('Style','PushButton','String','Push','Position',[30,60,80,20],...
'CallBack','disp(''You are pressed a push button'')');
close_btn = uicontrol('Style','PushButton','String','Close','Position',[30,5,80,50],...
'CallBack','close');
icon_file = fullfile(pwd, 'close.png')
str = ['<html><img src="file://' icon_file '"></html>']
set(close_btn,'String',str);
but it leaves me with an empty button.
If I deliberately use a filename that does not correspond to an existing file, I see a broken image icon:
So I am reasonably sure that the basic syntax and file path stuff is correct but the image does not get rendered in the button.
Is there something else I need to do to make this work or is it all just part of Matlab's overwhelming strangeness?
The easiest way to put an image on a uicontrol (and specifically a button), is to use the CData property,
im_orig = imread(icon_file); % Needs to be true color, i.e. MxNx3
im_sized = imresize(im_orig,[80,50]); % size of the button
% str = ['<html><img src="file://' icon_file '"></html>'];
% set(close_btn,'String',str);
set(close_btn,'CData',im_sized);
I'm using properties files in my webapp to cater i18n needs. Sometimes the text that I'm translating needs to have individual styling. For example:
options.reduce.co2.label = To reduce your CO2 emission, click here!
Should actually be rendered as:
To reduce your CO<span class="subscript">2</span> emission, click here!
The diry fix would be to include this styling in my properties file. However, I really want to avoid this!
A more clean approach would be to split up all the parts of the text:
options.reduce.co2.label.part1 = To reduce your CO
options.reduce.co2.label.part2 = 2
options.reduce.co2.label.part3 = emission,
options.reduce.co2.label.part4 = click here
options.reduce.co2.label.part5 = !
However, this makes the property files a big mess of words rather than structured sentences.
How do you generally deal with this situation? I want to achieve maximum readability and maintainability for the developers.
I always use placeholders for this kind of stuff:
options.reduce.co2.label = To reduce your CO%s2%s emission, click %shere%s!
I have a base .docx for which I need to change the page header / footer image on a case by case basis. I read that python-docx does not yet handle headers/footers but it does handle Pictures.
What I cannot work around is how to replace them.
I found the Pictures in the documents ._package.parts objects as ImagePart, I could even try to identify the image by its partname attribute.
What I could not find in any way is how to replace the image. I tried replacing the ImagePart ._blob and ._image attributes but it makes no difference after saving.
So, what would be the "good" way to replace one Image blob with another one using python-docx? (it is the only change I need to do).
Current code is:
d = Document(docx='basefile.docx')
parts = d._package
for p in parts:
if isinstance(p, docx.parts.image.ImagePart) and p.partname.find('image1.png'):
img = p
break
img._blob = open('newfile.png', 'r').read()
d.save('newfile.docx')
Thanks,
marc
There is no requirement to use python-docx. I found another Python library for messing with docx files called "paradocx" altought it seems a bit abandoned it works for what I need.
python-docx would be preferable as the project seems more healthy so a solution based on it is still desired.
Anyway, here is the paradocx based solution:
from paradocx import Document
from paradocx.headerfooter import HeaderPart
template = 'template.docx'
newimg = open('new_file.png', 'r')
doc = Document.from_file(template)
header = doc.get_parts_by_class(HeaderPart).next()
img = header.related('http://schemas.openxmlformats.org/officeDocument/2006/relationships/image')[0]
img.data = newimg.read()
newimg.close()
doc.save('prueba.docx')
I try to make a photo-app that can read Qr-Codes with the ZXing-Library.
Most parts work but now somehow my LowLagPhotoCapture doesn't return anything useful:
var photoProperties = MediaProperties.ImageEncodingProperties.createJpeg();
mediaCaptureMgr.prepareLowLagPhotoCaptureAsync(photoProperties)
.done(function (_lowLagPhotoCapture) {
lowLagPhotoCapture = _lowLagPhotoCapture;
lowLagPhotoCapture.captureAsync()
.done(function (capturedPhoto) {
...
The MediaCaptureMgr works, I see a preview of the cam on the screen. But now I need to make a photo. The usual PhotoCapture didn't work with JavaScript and so I found this solution.
Somehow the lowLagPhotoCapture.captureAsync() crashes saying that lowLagPhotoCapture is empty. lowLagPhotoCapture is defined outside of this class because I need it later. But even if I pass the variable directly to the new method it fails =/
Any ideas what might go wrong with this?
Edit:
Okay, after every Async-operation I had a following nameless function and one exitOnError-function that was calles every time. If I remove thatv exitOnError-function out of .done(complete, error), it exits in the same place. But if I set a breakpoint on .captureAsync it goes 1-2 steps further, creates an ImageStream and exits somewhere there. Why the different behaviour with and without the breakpoint?
My code is simply looping through an xml file and creating 'pages' (which are later animated).
This has all worked fine but now I want to add a sprite over the entire contents of the page if the contents of the xml contain a URL.
At run-time I can see that the checks for the URL are being processed correctly and that the overlay is being generated, but I cannot "see" it on the page.
The following code is located in a for loop for every page in the xml file:
var page:Page = new Page(); //MovieClip in my library
// ... other stuff
var textMC:FadeText = new FadeText(xml); //load the text from the xml fragment for this page
//if the text contains a URL (using RegExp)
if(textMC.hasLink())
{
var button:Sprite = new Sprite();
button.graphics.beginFill(0x000000);
button.graphics.drawRect(0, 0, 1, 1);
button.name= textMC.getLink();
button.x = button.y = button.alpha = 0;
button.width = rectangle.width;
button.height = rectangle.height;
button.buttonMode = true;
button.addEventListener(MouseEvent.CLICK, goToUrl, false, 0, true);
page.addChildAt(button, page.numChildren);
}
//... more code - such as add page to stage.
From the console (using FireBug and FlashBug) the button is being created, but I cannot see it on screen so I am guessing the addChild bit is at fault.
What is wrong and how do I fix it?
[edit]
Having set the alpha to 1 I can see that the overlay IS being added to the page, but it is not changing my cursor or responding to mouse clicks.
I now believe it is something wrong with the XML. It is correctly parsed XML (otherwise FlashPlayer would throw exceptions in my face) and it appears that this code works on every page except the second. Further more, if the second page is set as visible (a flag in the XML determins if the page is created or not) then none of the other pages overlay works.
Sorry to necro this thread but one thing I can think of is that because you specify a z-position to place your page it might be that the z-position generated by (i+1) is not the next one in line. AS3 doesn't allow display-objects to be placed on 'layers' with empty 'layers' between them which was allowed in AS2.
My guess is that during the loop at one point or another the loop doesn't generate a page which leaves an empty layer. The reason why the stage.addChild(page) actually works is because it simply searches for the next empty layer in that stack because you don't specify it.
button.x = button.y = button.alpha = 0;
set alpha to 1
button.alpha = 1;
and check for rectangle.width , rectangle.height
last thing, check for textMC.hasLink() if its true or not. If its true, there is another problem with your code that is not related to this sample code.
Illogical answer:
Replaced stage.addChildAt(page,i+1); with stage.addChild(page);.
I was clutching at straws. Have spent FAR too long working on this blip, but it works! I don't know WHY it works, and at this point I don't care; IT WORKS!!! (sorry for the unprofessionalism however I have spent two and a half days working on this and have just got it working!)
If someone wants to explain why it works, feel free. I would VERY much prefer to learn why this occurs that struggle to work around it.
