Initializing dialogs

Hi folks,

I'm struggling with dialogs (again). I want to initialize a dialog before it is shown on screen, but I can't do image generation, font lookups, or measure the panes before the dialog is displayed (i.e. have a screen representation). When displaying "normal" interfaces using capi:display, I have two options:

1) Creating the interface with :display-state :hidden, display it, make my initialization, and then calling capi:show-interface
2) Implementing a interface-display :after method

None of these options are available when using display-dialog. Is there really no way to hook into that process??

Erik


PS.
Actually, I found a really ugly way, which sort of works: adding an "invisible" (e.g. 1x1 pixel) output-pane to the dialog, and call the initialization from its display-callback. But apart from its ugliness, it's also a bad solution if initialization takes some time, which makes the dialog "flicker" when it is redrawn

PPS.
This thread was interesting, as it could provide an alternative solution:

However, the wait-processing-events doesn't work on Cocoa, as it blocks the main event loop and hangs the application :(

Have you tried the :create-callback, either in the dialog interface or an
output-pane if you have one already?

Hello,

I asked something like that a while ago. This link was recommended to me:

Maybe it helps you.
