How to set tabfocus on radiobuttons in two columns

roseicollis

Hi!

I'm making an app with keyboard interaction so all the logic between widgets its throw TabFocus. I found a problem when I tried to put 4 radiobuttons and see that you have to use arrows instead of tab and spacebar so searching a little bit I found this example about how to do it with tab: "EXAMPLE":http://www.qtcentre.org/wiki/index.php?title=Button_groups_with_tab_focus

I added this new class "CustomButtonGroup" and applied it BUT I have another problem which is: I have 4 radiobuttons and I need them to be in 2 different columns (qrb_1 and qrb_2 on the left side, and qrb_3 and qrn_4 on the right one). To do that I used some layouts like this:

VlayQRB: where I have another widget upside the radiobuttons and then the Hlay2
Hlay2: to add 2 vboxlayouts to divide the radiobuttons into 2 columns
Vlay2L: for qrb_1 and qrb_2
Vlay2R: for qrb_3 and qrb_4

@
VlayQRB->addLayout(Hlay2);
Hlay2->addLayout(Vlay2L);
Hlay2->addLayout(Vlay2R);

Vlay2L->addWidget(qrb_1);
Vlay2L->addWidget(qrb_2);
Vlay2R->addWidget(qrb_3);
Vlay2R->addWidget(qrb_4);

CustomButtonGroup *cBG = new CustomButtonGroup;
qrb_1 = new QRadioButton(QString::fromUtf8(" Hi 1"));
qrb_2= new QRadioButton(QString::fromUtf8(" Hi 2"));
qrb_3 = new QRadioButton(QString::fromUtf8(" Hi 3"));
qrb_4 = new QRadioButton(QString::fromUtf8(" HI 4"));

cBG->addButton(qrb_1);
cBG->addButton(qrb_2);
cBG->addButton(qrb_3);
cBG->addButton(qrb_4);

The problem is that if I do that, the program closes unexpectly when I press space on a radiobutton BUT it works really fine if I only put qrb_1 and qrb_2 so I suppose that the program is becoming crazy with all that logic between so many layouts.

Any idea of how can I apply the CustomButtonGroup (which gaves me the logic about tab and spacebar I need) to my case (I need 4 radio buttons in 2 colums so I have 2 buttons on the right and 2 buttons on the left)??

Note: I tried too, creating a second CustomGroupBox and adding there qrb_3 and qrb_4 and it works fine but then, of course, I have 2 options checked on true (one for each custombuttongroup)

Thank you so much.

Hi,

Do I understand you right that if you have more than two button in the layout and group it crashes the application ?

Hi Sgaist.

Yes, but see that they are in 2 diferrent layouts so I think that here is the problem. Btw I've changed the radiobuttons to a combobox while I don't find another soluiton.

Did you run it through a debugger ?
