Exclusive Push Button

Ccmc

I want to toggle between several push buttons such that only one of them can be enabled at any given time - essentially, a set of Radio buttons that appear more like Push buttons. Also, they're located in completely different Group Boxes (although within the same dialog of course).

I'm slightly tempted to use n*n enable/disable signal-slots, but that does sound both ridiculous and onerous. Is there a different way to implement this? If so, can I also pull it off with Qt Designer?

Thanks.

Hi,

Use QPushButton's "autoexclusive":http://qt-project.org/doc/qt-5.0/qtwidgets/qabstractbutton.html#autoExclusive-prop property.

Thanks, but is there a way to do this for buttons with different parent widgets?

you can do the same like you would do with QRadioButtons, since "QButtonGroup":http://qt-project.org/doc/qt-4.8/qbuttongroup.html is based on QAbstractButtons.

I tried using the QPushButton "autoexclusive":http://qt-project.org/doc/qt-5.0/qtwidgets/qabstractbutton.html#autoExclusive-prop property, which worked wonderfully for the buttons within the same parent. This does not appear to apply to the buttons beyond the immediate parent, which is what I am trying to do.

Hi,

Did you use raven-worx suggestion ? QButtonGroup sounds like what you need.

think simpler :)

put your push buttons in a list, do just one slot, connect clicked signal of each to the only slot and use

@QPushButton *button = (QPushButton *)sender();@

may be focusWidget could be used in some context too, and uncheck all buttons in the list less the sender

hope this helps :)

Cheers!

and this should really be simpler than using a simple QButtonGroup?!
I would recommend this approach since is more error prone either...

since I quoted him I meant is simpler than his thinking, not others :)

which one is more error prone?

myself I found none of them as being error prone once everything is done right ... I reckon though what I suggested is more cumbersome :)

Cheers!
