Table Shortcuts Problem

[ankurjain]

Hi guys,

Following is my code. i get the table by a dll. My dll makes the table and gives the context menu over it. I set shortcuts for these also, but they are not working.

// dll cpp file QGrid.cpp
 
#include <QtGui>
#include "QGrid.h"
#include <QMessageBox>
 
/* Constructor creating the grid with 'r' rows 'c' columns and 'parent' parent.
 * It creates context menu for the grid.
 */
 
QGrid::QGrid(int r, int c,QWidget *parent) : QTableWidget(r,c,parent)
{
    createActions();
	setUpContextMenu();
    int change = -1;
    int rowNo = -1;
}
/* 
Constructor creating the grid with 0 rows ,0 columnms & 'parent' parent.
It creates context menu for the grid.
 */
 
 
QGrid::QGrid(QWidget *parent) : QTableWidget(parent)
{
    createActions();
	setUpContextMenu();
    int change = -1;
    int rowNo = -1;
}
 
/* Creates the context menu for the grid.  */
 
void QGrid::setUpContextMenu()
{
/*

 */    
	verticalHeader()->addAction(cutAct);
	verticalHeader()->addAction(copyAct);
	verticalHeader()->addAction(deleteAct);
	verticalHeader()->addAction(pasteAct);
	verticalHeader()->addAction(undoAct);
	verticalHeader()->addAction(redoAct);
	verticalHeader()->addAction(addrowAct);
	verticalHeader()->addAction(deleterowAct);
	verticalHeader()->setContextMenuPolicy(Qt::ActionsContextMenu);    
 
/*

 */ 
	addAction(cutAct);
    addAction(copyAct); 
    addAction(pasteAct);
	addAction(deleteAct);
    addAction(undoAct);
    addAction(redoAct);
    addAction(addrowAct);
	addAction(deleterowAct); 
 
    setContextMenuPolicy(Qt::ActionsContextMenu);
}
/*

void QGrid::createActions()
{
	copyAct = new QAction(QIcon(":/images/copy.png"), "&Copy", this);
	copyAct->setShortcut(tr("Ctrl+C"));
	copyAct->setShortcutContext(Qt::ApplicationShortcut);
	copyAct->setStatusTip(tr("Copy the current selection's contents to the "
                                 "clipboard"));

void QGrid::copy()
{
	QMessageBox::information(this,"COPY","From dll");
	int ind = 0;
	QString str,str1;
	int no = this->currentRow();
 
 
	foreach (QTableWidgetItem *i,this->selectedItems())
	{
//		this->clearSelection();		
		QString strPrint(i->text());
		strPrint+="\t";
		str+=strPrint;
		clip->setText(str,QClipboard::Clipboard);
