I have a main window and I want that when I maximize it the widgets inside it should automatically be resized ....
Is there any way I can do that ????
Yes. Use layout objects (such as QHBoxLayout or QGridLayout) to organize your widgets inside, and set the widgets' resize modes accordingly. Note that standard Qt-supplied widgets support resizing by default.
If you want to save you a lot of work, don't hand-code the ui. Use Qt Creator to create a ui file and then load this file dynamically using PyQt4.uic module. There is also a "static" approach that generates python code from Qt Creator ui files.

I am currently working on a GUI application using PyQt5 and QtDesigner. As I have to make it multi-platform (at least Ubuntu and W10) I will use the "Fusion" style to make it look similar on both platforms.
I was wondering if one could simply set the QApplication style directly in QtDesigner ? I know that a simple <<.setStyle("Fusion")>> will do the trick in the code, but does it exist within QtDesigner so the lines can be automatically generated ?
I'm trying to learn QtDesigner and how much it can be pushed before going into the code.
No, it is not possible to set the style through Qt Designer.
What Qt Designer does allow is to display the GUI with different styles if you select Form-> Preview -> ...
I am currently creating a GUI for an application and I want to make it frameless and add the minimize and close buttons myself. What I want to achieve can be seen in this answer:
The window structure I want to achieve
Since the GUI structure that I have in mind is really complex I really need that I have to use Qt Designer. Is there a way to achieve what is done in the answer above in the Qt Designer?
One way to achieve this is to create your application window as usual in Qt Designer, load the .ui file in the python via uic.loadUi and add it to the layout of box.contentWidget() instead of the edit in the linked example.
I need to be load QMovie in QtDesigner. I noticed that a lot of classes are not accessible from QtDesigner. I usually design in QtDesigner and I just load the ui file directly in my code. This way I never had to worry about implementing the GUI itself in code.
Is there a way I can do this without having to edit my code ?
So in summation I want to add QMovie to a horizontal layout in my main window.
QMovie is not a widget, so it makes no sense to add it to as layout.
You probably want a QLabel, which has a setMovie method for dispalying animated images. But note that a QMovie cannot play videos - if you want that functionality, you will have to use a Phonon.VideoWidget, rather than a QLabel.
I am trying to write a custom widget for the Qt Designer using only Python. I was following a couple of tutorials I found online but none of them were working or anything close to what I would call to be a minimum working example.
So my questions are:
What steps are involved to make a a custom widget appear in the Widget Box of Qt Designer?
If you can spare the time: Please provide a minimum working example (like a widget with a label in it saying "A truly minimal working Qt custom widget example").
Or is it maybe not possible at all to include a custom widget using only python?
There are very few examples available on how to make a custom widget in pyqt. I wrote this article with a working example: Making a Custom Widget in PyQt
Here is the answer to your question #3: How do I use promote to in Qt Designer in pyqt4?
I am using PySide and it works the same way. This method works directly with your Python custom widget code. You do not need to write any separate plugin code.
After you have promoted your custom widget, you can right click on it and add your signals with "Change signals/slots..."
I would recommend putting all you widgets in a YourCostumWidgetsPack.UI file, and then when you load this file in Qt Designer, in addition to the UI you are working. It will load all your custom widget information.
I found this article to be your answer: https://doc.qt.io/archives/qq/qq26-pyqtdesigner.html
But, I haven't been able to install it in Qt Designer though :D
I am working on Qtdesigner for generating a GUI for my python app.
The problem is that I had manually made the widgets and then compiled it to py. But then I found out that the components did not resize when maximised.
So I opened the .ui file in designer and selected the group box for my widgets and chose layout in grid by right clicking on it.
Even now the widgets do not resize on maximising....
Do I have to do something else ???
Thanks a lot...
To have the widgets resized with the window, you must apply a layout to your top-level object (usually QMainWindow), and then place your new widgets where you want in the layout (and maybe other layouts for a more complicated window).
NOTE: the menu items allowing to apply a layout on the main window will be available only once you have placed your first widget in it.
