Bug report #12671

Cursor icon is too small on HiDPI screen

Added by Alessandro Pasotti over 8 years ago. Updated almost 6 years ago.

Affected QGIS version:master Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:fixed/implemented
Crashes QGIS or corrupts data:No Copied to github as #:20778


Cursor icon size is hardcoded to 16x16 in many parts of the code (for example: https://github.com/qgis/QGIS/blob/master/src/app/qgisapp.cpp#L2317)

this makes the cursor very difficult to see.

The modification I suggest is to add a new QgsApp method that returns the zoom factor, calculated on a 96 dpi base, this will allow to resize all GUI parts by multiplying by the zoom factor.

To get current DPI you can use (Python code):


The very same method could be used to resize icons and other GUI elements.

I have a working prototype and I can fix the C++ side for cursor icons that are
- scalable
- SVG-based
- themable

but I'm not that good at SVG for creating the icons themselves any volunteer?

we need the icons that are listed in this file:
