Hello.
On the main window there is a progress bar that I want to change from another class A that works in a different thread.
I can change the value using the signals and slots that are configured inside class A (there is a public slot setValue(int)), but how do I change the visibility of the bar progress from another thread?
connect(this, SIGNAL(progressBarValue(int)), ui_progressBar, SLOT(setValue(int))); //work
connect(this,
SIGNAL(setWidgetColor
(QString)), ui_infoWidget,
SLOT(setStyleSheet
(QString)));
//work connect(this, SIGNAL(progressBarVisible(bool)), ui_progressBar, SLOT(setVisible(bool))); //don't work
connect(this, SIGNAL(progressBarValue(int)), ui_progressBar, SLOT(setValue(int))); //work
connect(this, SIGNAL(setWidgetColor(QString)), ui_infoWidget, SLOT(setStyleSheet(QString))); //work
connect(this, SIGNAL(progressBarVisible(bool)), ui_progressBar, SLOT(setVisible(bool))); //don't work
To copy to clipboard, switch view to plain text mode
Set visible for QProgressBar
