Layout Problem
Message 1 in thread
Hi,
Qt4.1.2
I have to layout some widgets(pushbuttons,labels) on a Frame
The requirement is such that they are divided in to two blocks:
_________
_________
| | space
| |
|widgets |
<---------------------------------------------------->|widgets |
|_________|
|_________|
So basiaclly one set of widgets at left side and other set at right side
of main window.
I have one Grid Layout for Left set of widgets, Second GridLayout for
Right set of widgets. Then I take a outer Grid Layout and add space
between them like this:
OuterGrid->addLayout(LeftGridlayout,0, 0, 1, 1)
spacerItem1 = new QSpacerItem(100, 20, QSizePolicy::Expanding,
QSizePolicy::Minimum);
OuterGrid->addItem(spacerItem1);
OuterGrid->addLayout(RightGridlayout,0, 2, 1, 1)
The problem is no matter what I set the size of spacer,it doesnot expand
and I have Left and Right set of widgets like this:
_________ _________
| | space | |
<--------->|widgets |<------------>|widgets |<--------->
|_________| |_________|
How can I set the spacer to take maximum space between left and right
set of widgets. As seen above I have set the horizontal strech policy
to: QSizePolicy::Expanding
Thanks.

Have you tried a QHBoxLayout as outer layout? I see no reason for a
QGridLayout here and it may actually be the reason. If I'm not mistaken
the GridLayout is makeing all 3 columns the same size and places the
contents centered in it.

Thanks,But I am using Grid Layout because there is a chance that in
future more widgets can be added.

Well, then there's no way to achieve what you want. Another way would be
to use a hbox layout for these 3 things and put that into the grid
layout.

Will try that thanks.
Also I have a pushbutton in one (Left) Grid layout. Caption of that
changes at run time. So I need to change the size of button.
When itry to change the size of button nothing happens.
I tried resize() and adjustSize() but button just wont expand.
Any ideas on this?
Thanks

You could calculate a sizeHint based on the length of the longer piece of text
and use this in a re-implemented sizeHint() for the widget.

I used that way thanks much.
Now the button is able to resize based on the text it contains.
However that has created another one.
I have a small pushbutton next to expanding button like this:
______ _
|______| |_|
A B
1). Now when A expands B doesnot appropriately move with it and is
sometimes overlapping with button A, Like this:
__________ _
|__________||_|
A B
2). On the other hand when A shrinks, B doesnot come closer to A:
__ _
|__| |_|
A B
I want the distance between A and B to be constant. How can I achieve
that. I have done numerous trails but no luck.
Thanks.

As Andreas said, try a QHBoxLayout:
QHBoxLayour* outer = new QHBoxLayout;
outer->addLayout(LeftGridlayout);
outer->addStretch();
outer->addLayout(RightGridlayout);
setLayout(outer);
