[Qt-interest] Layout issue

[Malyushytsky, Alex]

If I assume correctly, you would like to have  label and edit control being resize  independently from check boxes.
Putting them in the same layout makes their sizes dependent on each other.

Solution is based on what you want to achieve.

You can try to keep work mostly with only your widget grid layout.
In this case when you add/remove checkboxes you should also remove edit control ( I would place them in the independent horizontal layout anyway)
And re-add it with add function which specifies 'rowSpan' according to the current number of checkboxes.

But I would suggest give each group of controls its own layout like on the picture in the attachment. 

Make the widget layout vertical layout, group label and edit control with horizontal layout,
Group all the checkboxes in the grid layout. (If you decide to create last layout dynamically you might need to use invalidate on widget layout, or you can just to correct layout margins )

Hope this helps,
  Alex





In this case you should not put them in the same layout.
Cause grid layout 

So I would suggest to change layout structure (see attachment):
You will have 3 layouts
1.

Try to call invalidate() on layout after changes.

Hello forum,


I have a label and line edit which is horizontal layout and this layout is in turn inside the grid layout.

I have declared a private slot that responds to  text changed signal of the line edit.


The slots adds check boxes dynamically to the grid layout. Grid layout is the main layout of the class that i have sub-classed form QWidget.


When i press 4, two four check boxes added dynamically to  the layout. Then again when i press 1 , previously added 4 check boxes are removed and the new one
check box is added to the layout. But there is the extra space which was allocated while adding 4 check boxes. Those spaces remains ?


Any hint to maintain the size of the widget dynamically while adding and removing check boxes from the layout?



Regards
Sajjad
