User Expandable QPushButton in Qt application
Hi. I have a QPushbutton in my application. Is there any way to make QPushButton as user selectable and expandable when the user drag the border of the button.
Well, not directly
But QSizeGrip can be used to make a fast / not so fancy / hack-ish version
Note, you need to handle deselecting it again and remove the QSizeGrip etc.
the code is not complete for really using QSizeGrip.
For a more full version using sizing object , you can peek at this
It can work for normal widgets too with only slight modification.
Disclaimer. Just for fun code. Ugly , incomplete and hackish. #include <QSizeGrip> #include <QGridLayout> ... QWidget *the_widget_you_scale=ui->pushButton; /// BIG FAT NOTE: PushButtons used fixed height so it wont scale in that direction unless u disable it. the_widget_you_scale->setWindowFlags(Qt::SubWindow); QSizeGrip * sizeGrip = new QSizeGrip(this); QGridLayout * layout = new QGridLayout(the_widget_you_scale); layout->addWidget(sizeGrip, 0,0,1,1,Qt::AlignBottom | Qt::AlignRight);
@mrjj : Thanks for the reply. It works fine.
super. the code need a bit more of tweaking but it can work ok.
I used a message filter to check FocusIn and FocusOut events and added the
Widget into the "sizer" or removed it from it.
