QPushButton::setEnabled( true ) not working

[unshaven]

Hallo,

on a MainForm, I stacked a few widgets (in designer, partially overlapping, some visible by default, some not).
I have a QWidget ontop of some other things, which has three buttons on it, and a QLineEdit above them.

Those buttons are already set disabled (enabled not checked) by QtCreator designer once in a while, even if I set them to enabled again.
The widget is invisible normally, only sometimes I make it visible to show the buttons & lineedit.
Now, in the code, before using the buttons, I set everything enabled explcitly, to make sure.
But it doesn't work, and the assert at the end fails:

ui->widgetPanel->setEnabled( true );
 
    ui->btnNo->setEnabled( true );
    ui->btnYes->setEnabled( true );
 
    ui->widgetPanel->show();
 
 
    Q_ASSERT( ui->btnNo->isEnabled() );

ui->widgetPanel->setEnabled( true );

    ui->btnNo->setEnabled( true );
    ui->btnYes->setEnabled( true );

    ui->widgetPanel->show();


    Q_ASSERT( ui->btnNo->isEnabled() );

To copy to clipboard, switch view to plain text mode 

What could be the cause of this? Does Qt have problems with layers of widgets, even if some are invisible?
It was working for a while, though, and I was changing sizes and moving widgets around, then it stopped.
(and I did check in the "widget tree" that everything is correct in the hierarchy)

Hi,
Qt dont have a problem about layering.
I think you call "enabled button" at the wrong position. So, the enable button not changed.
Can you share your complete code, so we can check that.

Best regards,
