What's the easiest way to make components visible/invisible in a VBox/HBox so that they "collapse" their real estate. When you just set visible=false, the space for the component is still reserved in the associated VBox/HBox. In addition, setting width=0 or height=0 collapses the space for the component but doesn't collapse the gap space between components.
Is there an easy way to keep components in a VBox/HBox so they are still available via Actionscript but make them invisible *AND* also collapse their real estate (including gap space)? A common example: I have a form that shows either a combo box *or* a text box depending on selections made by the user. When the form changes from one to the other, I want to keep both controls but make one invisible (and collapse the associated space). I can do this with a Canvas using absolute layout (I just make the controls overlap and then set one visible and the other invisible), but I'm tyring to get it to work in a VBox/HBox form if possible.
