qt-designer

Feeling really stupid, right now, but the title says it all: How do you start the QtDesigner? I've installed PyQt5 via pip and I believe to have identified the directory it's been installed in as C:\Users\%username%\AppData\Local\Programs\Python\Python36\Lib\site-packages\PyQt5 Now what? There are a lot of .pyd files, some .dll's, too, but nothing executable (well, except a QtWebEngineProcess.exe in ...\site-packages\PyQt5\Qt\bin , but that doesn't sound like what I'm looking for. The latest PyQt5 wheels (which can be installed via pip) only contain what's necessary for running applications,

I designed a QMainWindow with QtCreator's designer. It consists of the default central widget (a QWidget ) which contains a QVBoxLayout with all the other widgets in it. Now everything I want, is that the QVBoxLayout automatically occupies the whole central widgets rectangle space. How can I do this? I didn't find any usable property neither in the central widgets properties nor the QVBoxLayout's ones. Georg Schölly You don't have to create a QVBoxLayout manually. Just select your central QWidget and press a make-layout button. Jaime Ivan Cervantes If you want to do it with code instead of

I made a "widget" in Qt Designer with about a dozen controls organized into horiz. and vert. layouts. Oddly, every horizontal layout wants to be some large size, about 400 px wide, when the whole form is set to be 275px wide. Buttons etc contained within are too wide for the form. When I resize the widget form vertically or horizontally (sometimes with the max width turned off) the various layouts won't resize. Manually setting widths (or min widths, or max widths) may affect the sizes of the controls, but not their spacing within the layout. Spacers inserted to keep some controls at the top

Today I have ported my application from Qt5.5 to Qt5.6RC. Running it on my high dpi screen the widgets appeared tiny. After reading this and setting QT_AUTO_SCREEN_SCALE_FACTOR to "1" at least it is usable again. However they say : In the longer term, the application should be adapted to run unmodified: 1) Always use the qreal versions of the QPainter drawing API. 2) Size windows and dialogs in relation to the screen size. 3) Replace hard-coded sizes in layouts and drawing code by values calculated from font metrics or screen size. Not all style sheet attributes support em (".. from font

I'm using the Qt Designer. I want to create a QVBoxLayout which will automatically expand to fill the whole window. The layout of the QVBoxLayout remains fixed. How can I cause the QVBoxLayout to expand and fill the entire window through the designer? After creating your QVBoxLayout in Qt Designer, right-click on the background of your widget/dialog/window (not the QVBoxLayout , but the parent widget) and select Lay Out -> Lay Out in a Grid from the bottom of the context-menu. The QVBoxLayout should now stretch to fit the window and will resize automatically when the entire window is resized.

I would like to know the "best practice" to change the behavior of some buttons to do the following: I want with a click to appear a menu. Or when you drag this same button you could drop it in another and this will "draw" a line connecting them. Here is an Example: The idea is to connect those "jack" buttons to any other "input" buttons. I was using the Qt designer and I realize that the buttons properties only the "acceptDrops" property is listed, but I can't make it work. Signals/Slots doesn't list something about dragging or dropping. So I think that the only way to do it is creating a

I want to make a group box shown only when a radio button is selected. I managed to do that by connecting the toggled(bool) signal of the radio button to the setShown(bool) slot of the group box. The problem is that the radio button is initially deselected but the group box is initially shown so I have to select/deselect the radio button to make it disappear. Is there any way I can make the group box initially invisible in Qt Creator Designer without having to do it in code? You can't. The visible property seems to be voluntarily removed from the property editor of Qt Designer and you can't

So, I'm trying to make a UI for a python code I have, but keep stumbling up on problems... Right now, all the code does is make a window, with 2 texteditor boxes, and one button. When the button is pressed, it prints 'Test'. I used QTDesigner to make the UI, then PyQt5 to convert it to python, and edited the code. My code: # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'widget.ui' # # Created by: PyQt5 UI code generator 5.9 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_Widget(QtGui.QWidget): def
