How to use the Qt3 Support members in Qt4?

[Cutey]

Hi Folks,

In my project(Qt4) I'm using

void QGridLayout::addColSpacing ( int col, int minsize )

void QGridLayout::addColSpacing ( int col, int minsize )

To copy to clipboard, switch view to plain text mode 

the above method but I'm getting the following error " 'addColSpacing' : is not a member of 'QGridLayout'. "

Can any one help me in this regard..!!!

try to use this

void QGridLayout::setColumnMinimumWidth ( int column, int minSize )

void QGridLayout::setColumnMinimumWidth ( int column, int minSize )

To copy to clipboard, switch view to plain text mode

You shouldn't use Qt3 support members in new code. Anyway, if you insist, add this to your .pro file:

QT += qt3support

QT += qt3support

To copy to clipboard, switch view to plain text mode

Yup I got it. Thanks folks...
But still I'm not meeting my requirement. FYI, Please look into the attachment.

There you could find collections of "checkboxes" in one side and other side "spinboxes & checkboxes".
I wanted to reduce the width of the spinboxes. I kept everything in a grid layout and I have tried setColumnMinimumWidth, setRowMinimumHeight, setColSpacing & etc., but nothing works...

Can any one help in this regard..........?

you can set Size Policy of spinBox to Fixed.

I tried the following method but I'm getting error( 'QSizePolicy::QSizePolicy' : cannot access private member declared in class 'QSizePolicy' ).

spnBx->setSizePolicy(QSizePolicy::Fixed)

How to get this property..???

use this use

void QWidget::setSizePolicy ( QSizePolicy::Policy horizontal, QSizePolicy::Policy vertical )

void QWidget::setSizePolicy ( QSizePolicy::Policy horizontal, QSizePolicy::Policy vertical )

To copy to clipboard, switch view to plain text mode

in your case, your code should look like

spinBox->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);

spinBox->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);
