控件支持键盘操作

支持键盘删除操作

private void hookKeybordActions() {

viewer.getControl().addKeyListener(new KeyAdapter() {

public void keyReleased(KeyEvent event) {

handleKeyReleased(event);

}

});

}

 

功能键（比如Tab，shift，ctrl等）前面不是以0开头，其它键是以0开头的

protected void handleKeyReleased(KeyEvent event) {

if (event.character == SWT.DEL && event.stateMask == 0) {

deleteAction.run();

}

 

 

public class DeleteAddressAction extends Action {

private AddressView view;

public DeleteAddressAction(AddressView view, String text,

ImageDescriptor imageDescriptor){

super(text, imageDescriptor);

this.view = view;

}

public void run()

{

AddressManager.getManager().removeAddresses(

view.getSelectedAddresses());

}

}

 

ImageDescriptor deleteImage = ImageKeys

.getImageDescriptor(ImageKeys.IMG_TOOL_DELETE);

deleteAction = new DeleteAddressAction(this, "", deleteImage);

deleteAction.setDisabledImageDescriptor(ImageKeys

.getImageDescriptor(ImageKeys.IMG_TOOL_DISABLEDELETE));

 

}
