Here is the call graph for this function:| void QGtk3Storage::populateMap | ( | ) |
Populates a map with information about how to locate colors in GTK.
This method creates a data structure to locate color information for each brush of a QPalette within GTK. The structure can hold mapping information for each QPlatformTheme::Palette enum value. If no specific mapping is stored for an enum value, the system palette is returned instead of a specific one. If no mapping is stored for the system palette, it will fall back to QGtk3Storage::standardPalette.
The method will populate the data structure with a standard mapping, covering the following palette types: \list
The method will check the environment variable {{QT_GUI_GTK_JSON_SAVE}}. If it points to a valid path with write access, it will write the standard mapping into a Json file. That Json file can be modified and/or extended. The Json syntax is
If the environment variable {{QT_GUI_GTK_JSON_HARDCODED}} contains the keyword true, all sources are converted to fixed sources. In that case, they contain the hard coded HexRGBA values read from GTK.
The method will also check the environment variable {{QT_GUI_GTK_JSON}}. If it points to a valid Json file with read access, it will be parsed instead of creating a standard mapping. Parsing errors will be printed out with qCInfo if the logging category {{qt.qpa.gtk}} is activated. In case of a parsing error, the method will fall back to creating a standard mapping.
