If you're interested what the above changes look like, I created an example PyQt5 app with a dark theme. The nice thing about this is that it introduces no external dependencies. tColor(QPalette.HighlightedText, Qt.black) tColor(QPalette.AlternateBase, QColor(53, 53, 53)) # Now use a palette to switch to dark colors: # Force the style to be the same on all OSs: But you can quite easily create one yourself with the following code: from PyQt5.QtCore import Qt This allows users to dynamically change the theme of an application developed with PyQt5 (or using analogous logic in C++, Qt5) to either a light or dark theme.ĭisclaimer: Obviously I am the maintainer. Light_(lambda: toggle_stylesheet(":/light.qss"))ĭark_btn = QPushButton("Toggle dark.", parent)ĭark_(lambda: toggle_stylesheet(":/dark.qss")) Light_btn = QPushButton("Toggle light.", parent) # more logic for creating top-level widgets, application logic. Now we can add generic application logic that can use this function in a signal/slot mechanism (using a lambda as a convenient wrapper, if needed, to provide the path to the stylesheet toggler): # add logic for setting up application
#Texstudio dark theme full#
:path: A full path to a resource or file on system ''' # get the QApplication instance, or crash if not set app = QApplication.instance() if app is None: raise RuntimeError("No Qt Application found.") file = QFile(path) file.open(QFile.ReadOnly | QFile.Text) stream = QTextStream(file) app.setStyleSheet(stream.readAll())

def toggle_stylesheet(path): ''' Toggle the stylesheet to use the desired path in the Qt resource system (prefixed by `:/`) or generically (a path to a file on system).

You may then use the function as a slot to a Qt signal (warning: I primarily develop using C++, so there may be small errors in my code for the signal/slot mechanism). In response to a comment, the easiest way to adjust the stylesheet to use either the light or the dark stylesheet dynamically is to wrap it in a function. To use it in PyQt5, simply add the following lines to a project: import sysįrom PyQt5.QtCore import QFile, QTextStream This was (hard) forked from the excellent QDarkStylesheet, which I felt had theme issues in numerous areas, so I modified it extensively for my own needs and added a light theme. No, but you may use my fairly comprehensive stylesheets that should look excellent on most platforms (it's inspired by KDE's Breeze Theme, which is a dark theme that is quite elegant).
