Q: How do I update the dimensions of a group when I 'grab' a control? 'Grab' is a really simple way of moving an object in 'browse' mode: Just 'grab me' in a mouseDown, and the object tracks the mouse until mouseUp (see the docs).
There is, however, a problem when you 'grab' a control in a group. The dimensions of a group do not automatically change to fit the repositioned control, nor is the group's formattedRect updated. This means you can easily drag an object out of sight to an inaccessible position. This is a 'bad thing'. It took me a while, but the trick here is to understand that the formattedRect of the containing group is only updated when a geometric property of a control (top, bottom, left, right, width, height etc) is changed. The following is a simplified group script: This fails to update the rect of the group... on mouseDown --| User clicks and drags a control in the group grab the target end mouseDown on mouseMove --| Resize the group... set the rect of this group to the formattedRect of this group end mouseMove This works... on mouseDown grab the target end mouseDown on mouseMove --| Force the formattedRect to update... set the top of the target to (the top of the target)+1 set the top of the target to (the top of the target)-1 --| Now the group can be resized... set the rect of this group to the formattedRect of this group end mouseMove Maybe this will help someone searching the archives. /H _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
