Python pyqt5 install#
You can install PyQt by installing Python and using pip with this command: pip install PyQt5 You'll need a little bit of Python coding to follow this tutorial. First, we’ll build a Hello World app before building a more useful desktop app for freelancer developers to calculate their taxes and hourly rates. It might be less popular, but I’m going to show you how effective PyQt5 can be for producing a desktop app. Qt is a graphical user interface toolkit for building desktop applications. PyQt5 is the interface that lets you use the C++-based Qt library from within Python. One popular option for developing cross-platform desktop apps is Electron and JavaScript. There are also times when an app has to be very memory efficient and will need to have low latency (graphic intensive apps, for example).
Python pyqt5 windows#
For instance, apps like Adobe After Effects or Word are still mainly used on the desktop so they can use dialog windows and keyboard shortcuts to improve the user's workflow. You can also use the hide mode with the QTableWidget for visualizing options by using a check button (yor desired dropdown checkbox group).Web apps are very popular, but there are still times when only a desktop app can deliver a great user experience. ()Īfter running it, you can observe in following image that it is possible to scroll all 36 items and to realize multiple selection with them.

Python pyqt5 code#
Code looks as follows: from PyQt5.QtCore import Qt Why can you not use a QTableWidget? I modified above code for including your long list and some labels for creating a similar context with your form. In following images it can be observed multiple selection by rows: I used it for printed in this kind of object ( QTableWidget) the values of each field in attributes Table of active layer as it can be observed in following image. W.setWindowFlags(Qt.WindowStaysOnTopHint) W.setWindowTitle('Example with QTableWidget')
However, you can also use a QTableWidget object whose ExtendedSelection option is already activated by default. QComboBox objects allow only single selection because they don't have ExtendedSelection option (as QListWidget objects) for activating multiple selection. Self.model().itemCheckStateChanged.emit() (self.afterActivated)įor i in range ( self.model().rowCount()): It's however possible to fix it, albeit in a slightly hackish way class CheckableComboBox2(QgsCheckableComboBox): The problem is that this signal is emitted when the combobox is opened and there's a single selected item, which is NOT the currentIndex It relies on the QCombBox activated signal to toggle on/off its items. QGIS defines its own QgsCheckableCombobox, which is unfortunately broken ( ).

# Update the text when an item is toggled tItemDelegate(CheckableComboBox.Delegate()) # Make the lineedit the same color as QPushButton # Make the combo editable to set a custom text, but readonly # Subclass Delegate to increase item height For anyone interested, here is an implementation of a CheckableComboBox.
