# QWhatsThis
|
||||
|
||||
### Tooltip Colors
|
||||
|
||||
QWhatsThis uses `QPalette::toolTipText` and `QPalette::toolTipBase` for its colors: unfortunately, these are not influenced by the stylesheet. To modify these, you can change the colors for `QPalette::ToolTipBase` and `QPalette::ToolTipText`. An example can be found in [whatsthis.py](/example/whatsthis.py).
|
||||
|
||||
A simple example of modifying the tooltip palette for the `QWhatsThis` style is as follows:
|
||||
|
||||
**C++**
|
||||
|
||||
```cpp
|
||||
#include <QApplication>
|
||||
#include <QColor>
|
||||
#include <QPalette>
|
||||
|
||||
int main(int argc, char* argv[])
|
||||
{
|
||||
QApplication app(argc, argv);
|
||||
|
||||
auto palette = app.palette();
|
||||
QColor green(0, 255, 0);
|
||||
QColor blue(0, 0, 255);
|
||||
palette.setColor(QPalette::ToolTipBase, green);
|
||||
palette.setColor(QPalette::ToolTipText, blue);
|
||||
app.setPalette(palette);
|
||||
|
||||
...
|
||||
|
||||
return app.exec();
|
||||
}
|
||||
```
|
||||
|
||||
**Python**
|
||||
|
||||
```python
|
||||
import sys
|
||||
from PyQt6 import QtGui, QtWidgets
|
||||
|
||||
ColorRole = QtGui.QPalette.ColorRole
|
||||
|
||||
def main():
|
||||
app = QtWidgets.QApplication(sys.argv)
|
||||
|
||||
palette = app.palette()
|
||||
green = QtGui.QColor(0, 255, 0)
|
||||
blue = QtGui.QColor(0, 0, 255)
|
||||
palette.setColor(ColorRole.ToolTipBase, green)
|
||||
palette.setColor(ColorRole.ToolTipText, blue)
|
||||
app.setPalette(palette)
|
||||
|
||||
...
|
||||
|
||||
return app.exec()
|
||||
```
