How to create a slide-out window ?

I am really not happy with the scroll effect or "fly-in" effect using the following code -

QPropertyAnimation *animation = new QPropertyAnimation(mSlideWidget, "geometry");
animation->setDuration(500);

//Now animation to provide a fly-by effect
QRect startRect(80,0,0,300);
QRect endRect(80,0,500,300);
animation->setStartValue(startRect);
animation->setEndValue(endRect);
animation->start();

Its not as I want it to be.It should have a kind of slide- out effect from the position (x,y) = (80,0). Beyond that; that x < 80, it should not be visible. Can u please suggest how to do this ?

Currently the above code "expands" the widget from 0 width to width 500 which is not exactly what i want.

Hi, try

QRect startRect (-420, 0, 500, 300)

QRect startRect (-420, 0, 500, 300)

To copy to clipboard, switch view to plain text mode 

The widget should then move with fixed size and not expand from zero size.

edit: ah, did not read correctly: this will not fly-in from x=80.

I tried giving a negative x value only to find a displeasing effect ... any other way to do this ?

It should be like in this page -

Your examlpe could be achieved with the solution Ginsengelf. Or you have to set a mask to your widget and animate that.

I tried out the solution with starting rectangle QRect startRect( -420,0,500,300 ). Sure this works fine, but I would like how to set the mask so that the widget is visible only after its x >= 80

I was able to manage masking a particular region of the widget using setMask(). I have a small query regrading this. I want the masked region to remian valid even after the slide -out window is translated ( or moved ). How do I ensure this ?
