user-interface

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I want to make a desktop GUI that interacts with the user's files (with permission of course).

问题 Background : I need Command Link-like controls. Normally, I would use Qt's builtin QCommandLinkButton, but in this case I need to also support Right-to-Left layouts. Regrettably, QCommandLinkButton doesn't seem to respect Qt::RightToLeft when set explicitly via setLayoutDirection . There also doesn't seem to be a way to override the layout direction via style sheets. I tried to work around this issue by using QPushButton : I instantiated QPushButton and replaced its contents with a custom

问题 Is there some way I can create custom styles in wxPython? I searched all the docs and websites referring to wxPython styling and could find nothing. Do I have to create the custom style using the wxPython canvas? 回答1: wxPython uses native widgets in its core widgets as much as possible. Most of the widgets are going to be "native" to the system you are using, so unfortunately you can't fully manipulate how the control paints itself. Sometimes, you can modify widgets via the methods mentioned

问题 I'm using PyQt for Python, and am building a gui. I had a problem a few weeks ago where I had a function outside of the gui module modifying widgets within the gui (advanced progress bar, updating strings, etc.), and those modifications were not reflected in the gui until the function that had made the changes finished running. The solution to this was to simply call app.processEvents() after doing whatever modifications I wanted, which would immediately update the graphics of the window. But

问题 This is what I need in my node.js application: System tray icon changing this icon during application work menu after clicking on icon creation of windows with fields for login / password and confirmation buttons This is what I found: https://github.com/appjs/appjs - It looks good, but there is still no system tray support (it looks it will be done in some time) https://github.com/zcbenz/node-gui - It looks there is support for all I need, but I can't install it (I think this project is dead.

问题 I'd like to know how to center the contents a Text widget vertically and horizontally in Flutter. I only know how to center the widget itself using Center(child: Text("test")) but not the content itself, it's by default left aligned. In Android, I believe the property of a TextView that achieves this is called gravity . Example of what I want: 回答1: Text alignment center property setting only horizontal alignment.
