[kde-edu]: Cartesian plane on qt canvas

[Jason Harris]

Hi Trenton,

I think you just need to give your window a layout manager.  The plot 
widget should then resize itself automatically to match the size of the 
window.  Try this:


#include <qlayout.h>
#include <klocale.h>
#include <kdialog.h>

#include "trigviewer.h"

TrigViewer::TrigViewer(QWidget* parent, const char* name, WFlags fl)
         : QWidget( parent, name )

{
     view = new QWidget(this);

     QVBoxLayout *vlay = new QVBoxLayout( view, 0, spacingHint() );

     pw = new KPlotWidget( -50.0, 50.0, -50.0, 50.0, view );

     pw->setDefaultPadding();
     pw->setShowAxes( true );
     pw->setBGColor( QColor( "white" ) );
     pw->setFGColor( QColor ( "black") );
     pw->setShowTickMarks( true );
     pw->setXAxisLabel( i18n( "X-Axis" ) );
     pw->setYAxisLabel( i18n( "Y-Axis" ) );

     vlay->addWidget( pw );
     resize( 500, 500 );  //optional, you can put whatever dimensions 
you want here

     plotObjects();
}


let me know if that works,
Jason
