QCheckBox does not update unless mouse over it again
check not updated
@wainCam Can you please be a bit more specific about your problem?
What did you try? What did you expect to happen? What did actually happen?
I have a Qt Application built with Qt Creator.
I have check boxes on different tabs of a QTabWidget, and it has a video display window. It is keeps my computer pretty busy.
When I click on a checkbox, the check on the checkbox takes a while to show up.
If I quickly check the box and move by mouse away, the "check" in the box does not show up. I need to mouse over the check-box again for the check to be shown.
I have added a stateChanged() function for the "Display_box_fit" check box. When I update the text associated with the check box, this happens right away. I can set the state of another check box and the check in this box happens right away. However, the check for the "Display_box_fit" is slow, and if I mouse away (ie out of focus for the check-box), the check is never displayed on the check box.
No amount of repaint() calling in the "Display_box_fit_stateChanged()" function seems to fix the problem.
I have googled the problem for far too long and have found no good solutions.
It seems like a pretty fundamental issue.
Is there someway to get this to work without requiring the user to re-mouse over the checkbox to see its state?
I am using visual studio under windows with Qt5 under c++
ui.tabWidget->currentWidget()->repaint(); //ui.Display_box_fit->repaint(); //ui.Display_box_fit->parentWidget()->repaint(); //ui.Display_box_fit->parentWidget()->parentWidget()->repaint(); //ui.tabWidget->setCurrentWidget(ui.tab_debug); //ui.tabWidget->setCurrentWidget(ui.tab_Display);
Hi and welcome to devnet,
What version of Qt are you using ?
