displayObjectA can by masked by displayObjectB with the assignment displayObjectA.mask = displayObjectB;
This will cause only the portions of displayObjectA that are "under" displayObjectB to show through. Also, you won't actually see any of displayObjectB. There is an example in the docs that demonstrate this. It shouldn't be difficult to apply a similar solution to your problem. http://livedocs.adobe.com/flex/3/langref/flash/display/DisplayObject.html#mask For your particular problem can control the width of the masked DisplayObject with your slider. --- In flexcoders@yahoogroups.com, "ashlytu" <[EMAIL PROTECTED]> wrote: > > I have asked this question before,but i might not make it clear enough. > > I need to use the hslider to control how many percent of the image > will be shown in a panel,when I trag the slider to the zero, none of > the picture shows ,and when I drag it to the right edge, and the whole > picture is shown.Tim Hoff have told me a method ,but I guess I have to > use mask, cause the image cannot move, but I have to be controlled by > the Hslider. > > I don't know how to use the mask ,Would you please help me?Thanks!! > > > > Ashly >
