Scroll Multiple Child GUIs at the Same Time

Recommended Posts

I've searched the web and am turning up empty, so I'm hoping that someone here can help me out or point me in the right direction. This is the first time I've messed around with scrollbars and I can't seem to get things to work the way I want them to.

I've got a large GUI that has several child GUIs that display various bits and pieces of info. I'm trying to set it so that some of these child GUIs all move at the same time when a scrollbar is used. I tried using the more native code as shown in the Help files, and then tried Melba's stuff: '?do=embed' frameborder='0' data-embedContent>> and still no luck. All I can get it to do is scroll one child GUI at a time. I can't seem to figure out how to do multiple child GUIs at once.

In my example code (I just quick put it together to show what I'm trying to accomplish), how can I get $hGrandChild1 and $hGrandChild2 both to scroll up or down (at the same time) when I use a vertical scrollbar?

Thanks!

Lucid,

Can you please explain why you need so many child GUIs. Your example is less that clear about exactly what you are trying to achieve. :)

In the production code, the main reason for so many GUIs is that I'm using .PNG files (with transparency) for custom buttons. The only reliable method I've found to create a custom graphical button is to create a separate GUI for the button (using the typical Default, Hover, Pressed look and feel).

Lucid,

Fine, but what has that got to do with scrolling? :huh:

In my example, mentally replace $hGrandChild1 and $hGrandChild2 with something like $hButton1 and $hButton2. They're 2 separate button GUIs (based on .PNG images - such as "SHOW MORE INFO" and "CONTACT SUPPORT") that need to scroll vertically, along with some other label text, that's all on the $hChildGUI GUI.

The production code I'm currently hacking away at is like 6,000 lines of code - otherwise I'd post it here instead of my short example :)

So I either need a way to scroll both button GUIs at the same time, or a different way of making a transparent PNG-based button (that can exist - without flickering - on top of a larger background PNG file). The only way I can do it so far is to use GUI-based buttons.

Any suggestions? Thanks!
