What is "mouse action"? Perhaps you could disable the widget?

I guess there are no direct method to do. Probably you create your own cursor which is blank and set for the widget. This sounds crude but anyway try this. You might need to ignore all the mouse events if you dont want the widget to be disabled.

#include <QtGui>
 
class Widget : public QWidget
{
	public:
		Widget(QWidget *par=0) : QWidget(par)
		{
			QBitmap bitmap(32,32);
			bitmap.fill(Qt::color0);//initialize every thing to 0 bit
			QCursor cursor(bitmap,bitmap);//blank cursor
			setCursor(cursor);
		}
 
		bool event
};
 
int main(int argc, char *argv[])
{
 	QApplication app(argc, argv);
 	Widget w;
 	w.show();
 	return app.exec();
}

#include <QtGui>

class Widget : public QWidget
{
	public:
		Widget(QWidget *par=0) : QWidget(par)
		{
			QBitmap bitmap(32,32);
			bitmap.fill(Qt::color0);//initialize every thing to 0 bit
			QCursor cursor(bitmap,bitmap);//blank cursor
			setCursor(cursor);
		}
		
		bool event
};

int main(int argc, char *argv[])
{
 	QApplication app(argc, argv);
 	Widget w;
 	w.show();
 	return app.exec();
}

Thak you For your Replies,

I got another direct solution, we can use like following ,

int main(int argc,char *argv[])
{
QApplication app(argc,argv);
QMainWindow* wid=new QMainWindow;
app.setOverrideCursor(Qt::BlankCursor);
wid->show();
return app.exec();
}
Thanks,

app.setOverrideCursor(Qt::BlankCursor);

lol. Never thought of searching for it after going through some unneeded cursors in the predefined cursor list.
Good that you found out a more elegant solution.
