Detailed Description

Maintains consistent column sizes across layouts.

KColumnResizer is a helper class which can force columns of different layouts to keep the same width. It is useful to keep label columns consistent.

It works with QGridLayout and QFormLayout.

left: without KColumnResizer - right: with KColumnResizer

Here is a typical example:

void Window::createWidgets()
{
    QVBoxLayout *layout = new QVBoxLayout(this);
 
    QGroupBox *box1 = new QGroupBox();
    // Fill box1
    // ...
    layout->addWidget(box1);
 
    QGroupBox *box2 = new QGroupBox();
    // Fill box2
    // ...
    layout->addWidget(box2);
 
    KColumnResizer *resizer = new KColumnResizer(this);
    resizer->addWidgetsFromLayout(box1->layout(), 0);
    resizer->addWidgetsFromLayout(box2->layout(), 0);
}

In this example box1 and box2 children can be organized using QGridLayout or QFormLayout, resizer will ensure the first columns of the two QGroupBox stay the same width.

Member Function Documentation

addWidget()

void KColumnResizer::addWidget

(

QWidget *

widget

)

Add a single widget to the list of widgets whose width is monitored.

It is more common to use addWidgetsFromLayout(), but adding single widgets can be useful if you want to keep a single button the same width as a column in a layout.

Parameters

widget

The widget to add

Definition at line 182 of file kcolumnresizer.cpp.

addWidgetsFromLayout()

void KColumnResizer::addWidgetsFromLayout	(	QLayout *	layout,
		int	column = 0 )

Add all widgets from layout which are in column column to the list of widgets to manage.

Parameters

layout	The layout containing the widgets to add. KColumnResizer supports QGridLayout and QFormLayout.
column	The column number which contains the widgets. If layout is a QFormLayout, column should not be higher than QFormLayout::SpanningRole

eventFilter()

bool KColumnResizer::eventFilter ( QObject * , QEvent * event )

overrideprotectedvirtual

Reimplemented from QObject.

Definition at line 201 of file kcolumnresizer.cpp.

removeWidget()

void KColumnResizer::removeWidget

(

QWidget *

widget

)

Remove a widget previously added by addWidget or addWidgetsFromLayout.

Parameters

widget

The widget to remove
