hi!

is there some possibility in phab to init a widget as “unrealized” or
hidden so the widget isn’t shown at application start because later i
maybe want to show it

thanks!

One favourite trick is to set its position to large, negative values.
That way, you can realize it but no one will see it. When you want to see
the widget, change its coordinates to positive values.

thanks, but i was looking for a more generic solution

PtSetResource(widget, Pt_ARG_FLAGS, Pt_DELAY_REALIZE, Pt_DELAY_REALIZE);

why this flag can’t be modified/set in phab? my intention was to set this
property in design-mode

in docs there is: Pt_DELAY_REALIZE
in header: Pt_DELAY_REALIZE and Pt_DELAY_ACTIVATION for this purpose

No idea, oversight I guess. There is a palette file that needs
to be updated when new flags/resources are added. Wait a minute,
I do not think it would be useful in design mode, since PhAb instantiates
the widget, if the delay realize was set, you would not see the widget
in PhAb. Just a guess. In short, you could place it in a pre-realize
routine.

in docs there is: Pt_DELAY_REALIZE
in header: Pt_DELAY_REALIZE and Pt_DELAY_ACTIVATION for this purpose

I have never heard of Pt_DELAY_ACTIVATION, it could be a backwards
compatibility flags.

that would be exactly what I want, so the designer is able to prepare the
initial view of app, if the delayed widget is invisible, he can access it
via module-tree and make his resource-manipulations

in PhAb. Just a guess. In short, you could place it in a pre-realize
routine.
