How to fix blurry text in WxPython controls on Windows?
Blurry text in WxPython controls on Windows is often caused by a mismatch between the default font used by the controls and the scaling factor applied to the application. This can happen when the application is running on a high-DPI (High-Resolution) display. To fix blurry text in WxPython controls on Windows, you can try the following solutions:
Use a High-DPI Aware Manifest:
Create a manifest file for your WxPython application to indicate that it is DPI-aware. This will help Windows render the controls correctly on high-DPI displays. To do this, create a file namedyour_app_name.exe.manifest
(replaceyour_app_name
with the name of your application) with the following content:xml<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<application xmlns="urn:schemas-microsoft-com:asm.v3">
<windowsSettings>
<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
</windowsSettings>
</application>
</assembly>
Place the manifest file in the same directory as your application's executable.
Set Font Manually:
Set the font explicitly for WxPython controls to ensure a consistent look across different DPI settings. You can do this by setting the font for each control using theSetFont()
method. For example:pythonimport wx
class MyFrame(wx.Frame):
def __init__(self, parent, title):
super(MyFrame, self).__init__(parent, title=title)
# Set the font for the entire application
font = wx.Font(wx.NORMAL_FONT.GetPointSize(), wx.FONTFAMILY_DEFAULT, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_NORMAL)
wx.GetApp().SetFont(font)
# Rest of your code here
if __name__ == "__main__":
app = wx.App(False)
frame = MyFrame(None, "My Application")
frame.Show()
app.MainLoop()
Adjust DPI Scaling in Windows:
Adjust the DPI scaling setting in Windows to see if it improves the text quality. Right-click on the desktop, select "Display settings," and adjust the "Scale and layout" setting to a value that works best for your display.Use a Different Font:
Try using a different font for the WxPython controls. Some fonts may render better on high-DPI displays than others.
Remember that different WxPython controls may require different font sizes or settings to look good on high-DPI displays. Experiment with different settings and fonts to find what works best for your application and display.
