problem with a drag command

hi everyone, I have a problem with the drag command.
since I don't want to use coordinates, is it possible to use drag in some alternative method?
I don't want to use the coordinates because I wouldn't want to have problems if I have to change the screen resolution where they run my test.

Do you drag on same object, on different object ?

You can use coordinates based upon object ScreenLeft and ScreenTop properties.

The drag command in testcomplete needs co-ordinates.  You need to know the object to be dragged and the destination and that is, for the Drag method, co-ordinate based.


but!  Never fear... I've got a code for that.


In Javascript:


function dragCalculatedDistance(startObject, destinationObject) {
    var startPoint, targetPoint, dragX, dragY;
    // Drag from the center of object A to the center of object B

    startPoint = startObject.WindowToScreen(startObject.Width/2, startObject.Height/2);
    targetPoint = destinationObject.WindowToScreen(destinationObject.Width/2, destinationObject.Height/2);

    dragX = targetPoint.X - startPoint.X;
    dragY = targetPoint.Y - startPoint.Y;

    startObject.Drag(-1, -1, dragX, dragY); 

As noted in the comments, this will drag from roughly the center of the starting object to the center of the destination object.

Why automate?  I do automated testing because there's only so much a human being can do and remain healthy.  Sleep is a requirement.  So, while people sleep, automation that I create does what I've described above in order to make sure that nothing gets past the final defense of the testing group.

As per the documentation for the .Drag() method, initial coordinates are "relative to the object, it is not a screen coordinate." The distance to execute dragging for is also calculated as a relative distance between two objects.

So, (as it was mentioned by @BenoitB), proper use of relevant .ScreenLeft/.ScreenTop/.Left/.Top properties of the required objects will provide you with resolution-agnostic code for .Drag().
