    Hi,

    I'm looking for ideas.

    Our application uses three different font sizes (small, medium, large). I want to be able to change any of them on the fly and have the application update correctly. That is, if I change the medium font from size 10 to 12, I want all current widgets of size 10 to change to size 12 and of course, new widgets would come in at size 12.

    Currently, I have my own setFont and track the widgets there. Then when the font size is changed I can just set the font on the widget list to the new size and the display updates. This is slow and I'm having some troubles with QTreeWidgetItems (and sip).

    First a little background. This application runs standalone, but mostly we run it within Maya (which is now a QT app too). So I can't use QApplication.setFont because that would change Maya's fonts too. So it seems I do need a font manager of some kind.

    My biggest problem is the calls to QLabel and others that don't explicitly setFont. I have to find all those calls and do a setFont there.

    Does anyone have any easier suggestions as how to do global font changes and have them be live right away?

    Thanks,
    Howard

      In MainWindow you could use the following line:
      @ this->setStyleSheet(QString::fromUtf8("font: 10pt FreeMono;"));@

      to set FreeMono 12pt font globally...

      You can also limit the stylesheet to some widgets by properly defining the stylesheet, e.g:
      @ this->setStyleSheet(QString::fromUtf8("QLabel {font: 10pt;}"));@
      just to set font size only for QLabels...

      I hope it helps.
