I am developing an application which uses treeview. Initially, I used Qt designer for the GUI and after, compiled the ui file into python. Until now everything was just fine. Now I want to copy and paste the file on pressing Copy and Paste buttons simultaneously.
I watched and read many tutorials but they used re implementation of QPushButton. I can't adopt this technique because I used designer to create GUI and cant make changes in that file. Please help me to figure out that how can i use QEvents of my treeview.
I hope my question is clear.

I am using Qt Designer for creating GUI files all work well for me in Qt Designer GUI window but if I run the generated file in Python it the text context is cut short, I need to know why this is happening?
This image is the preview feature of Qt Designer:
This image is the output of the python file generated when the QtDesigner was converted to a python file and executed.:
I suppose you are new in PyQt5.Sooner or later you will understand that whenever you create something in Qt designer like a button or a label,this item will be completely static.That means that whatever you create will be 'stuck' there with the absolute coordinates you defined and absolutelly zero interactivity.Here comes layers and minimum-maximum sizes of widgets.You can apparently just drag more your labels width manually from Qt Designer but this approach will not get you very far.Because this topic is rather big ,i will suggest playing more with Qt Designer and the inputs you can provide on the right tab ,and watch some tutorial about PyQt5 like this:https://www.youtube.com/watch?v=FVpho_UiDAY&ab_channel=TechWithTim
I am working on QT Designer to build GUI App. I want to ask how add command for push button.
For example I want to apply this action :
self.NfmtLoginButton.clicked.connect(lambda: SecondScript.printme(self.NfmtPasswordEntry.text()))
Is it possible through the QT Designer. to be permanently saved. and no need to add all the commands again when generating new python script file from UI file.
No, it's not possible, but that should not be a problem, as the files generated using pyuic should never, ever be modified (the warning in those files is not to be undertaken).
Those files should always be left unmodified and only updated again with pyuic, as they are only meant to be imported in the actual program file, as explained in the official guidelines about using Designer (the "multiple inheritance approach is generally the most suggested).
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 developing the GUI for my application using wxpython and have most of the features down, except in the main frame/window I want to have a box for choosing a file (in this case, the input will have to be an excel file). Something similar to the standard filebrowser that is accessed whenever you choose "open" from a menu.
Below is an image to show exactly what I want...
You probably want a wx.FileDialog. It provides access to the default file dialog of the OS your app is running in. You can see an example of how it's used in the wxPython demo package. This tutorial also has some screenshots and sample code:
http://www.blog.pythonlibrary.org/2010/06/26/the-dialogs-of-wxpython-part-1-of-2/
The screenshot you show appears to be an interface to actually open the dialog. You can easily create that using sizers and basic widgets. Then just bind the open button to a handler that will show the dialog.
You might also want to take a look at the FileBrowseButton from wx.lib.filebrowsebutton (also in the demo).
There are a few other related widgets which you might be interested in too: wx.DirDialog, MultiDirDialog or wx.GenericDirDialog.
Assuming you know the basics of wxPython you can use wx.GenericDirCtrl and wx.ListCtrl to make nice browser
I'm using Qt Designer to create UI designs which I'm then converting into python code. Since I'm quite new to Qt I'd like to ask: is there a way I could implement a multi-screen application? I.e. having a next button clicked and getting a new set of options/widgets etc within the same window.
To be honest, I was developing using Kivy, and as slick as that is (especially with multiple screens) it depends on PyGame, which proves to be an enormous portability headache, so I had to switch to something else, and PyQt was the next feasible option (or so it seems).
It's called a QWizard. It is not called a multi screen application, but if you search for wizard instead, you find lots of information.
