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.

Qt Code: 
  1. // dll cpp file QGrid.cpp
  2.  
  3. #include <QtGui>
  4. #include "QGrid.h"
  5. #include <QMessageBox>
  6.  
  7. /* Constructor creating the grid with 'r' rows 'c' columns and 'parent' parent.
  8.  * It creates context menu for the grid.
  9.  */
  10.  
  11. QGrid::QGrid(int r, int c,QWidget *parent) : QTableWidget(r,c,parent)
  12. {
  13.     createActions();
  14. 	setUpContextMenu();
  15.     int change = -1;
  16.     int rowNo = -1;
  17. }
  18. /* 
  19. Constructor creating the grid with 0 rows ,0 columnms & 'parent' parent.
  20. It creates context menu for the grid.
  21.  */
  22.  
  23.  
  24. QGrid::QGrid(QWidget *parent) : QTableWidget(parent)
  25. {
  26.     createActions();
  27. 	setUpContextMenu();
  28.     int change = -1;
  29.     int rowNo = -1;
  30. }
  31.  
  32. /* Creates the context menu for the grid.  */
  33.  
  34. void QGrid::setUpContextMenu()
  35. {
  36. /* 
  37. This block adds the context menu over the vertical headers.
  38.  */    
  39. 	verticalHeader()->addAction(cutAct);
  40. 	verticalHeader()->addAction(copyAct);
  41. 	verticalHeader()->addAction(deleteAct);
  42. 	verticalHeader()->addAction(pasteAct);
  43. 	verticalHeader()->addAction(undoAct);
  44. 	verticalHeader()->addAction(redoAct);
  45. 	verticalHeader()->addAction(addrowAct);
  46. 	verticalHeader()->addAction(deleterowAct);
  47. 	verticalHeader()->setContextMenuPolicy(Qt::ActionsContextMenu);    
  48.  
  49. /* 
  50. This block adds the context menu over the grid.

  58.     addAction(addrowAct);
  59. 	addAction(deleterowAct); 
  60.  
  61.     setContextMenuPolicy(Qt::ActionsContextMenu);
  62. }
  63. /* 
  64. This function is creating the actual actions. Following functions are provided:
  65. Cut, Copy, Paste, Undo, Redo, Addrow, Deleterow.
  66.  */
  67. void QGrid::createActions()
  68. {

  70. 	copyAct->setShortcut(tr("Ctrl+C"));
  71. 	copyAct->setShortcutContext(Qt::ApplicationShortcut);
  72. 	copyAct->setStatusTip(tr("Copy the current selection's contents to the "
  73.                                  "clipboard"));
  74. 	connect(copyAct, SIGNAL(triggered()), this, SLOT(copy()));
