QT column occupied issue with add widgets

Question

Hi

I have a QGridLayout of rowspan 1 and columnspan 8.

I have 5 widgets to be placed in a raw and hence rowspan is 1 , but kept columnspan as 8 as I need three column space left in after third widgets . Something like below:

column 1 : label
column 2 : checkbox
column 3 : combo box
column 4 : EMPTY
column 5 : EMPTY
column 6 : EMPTY
column 7 : line edit
column 8 : push button

I am doing AddWidget (widget,startrow,startcol,rowspan,colspan) as below:
AddWidget(widget,0,0,1,1);
AddWidget(widget,0,1,1,1);
AddWidget(widget,0,2,1,1);
AddWidget(widget,0,6,1,1);
AddWidget(widget,0,7,1,1);

Why all widgets are adjacent to each other and there is no space left? Am I missing anything?

Answer 2

I got rid off the grid layout and returned back to hboxlayout. Added spacer in between to have the space in between widget.

Answer 3

Thanks but is it necessary to use the extra widget spacer?

If it is needed, why do we have start column if it does not have any sense?

Answer 4

or perhaps you should assign a value for setColumnMinimumWidth for columns 4,5 and 6? Perhaps they're defaulted to 0 width.

Answer 5

Unfortunately , setColumnMinimumWidth also did not help

Answer 6

is the gridlayout nested inside another container? Perhaps that is forcing the compression by constraining the expansion space? how about enabling expansion by adding a QScrollArea?
