Re: Question about modal dialog in gtk application

[silverburgh <silverburgh meryl gmail com>]

Jim,

Thank you.

Can you please help me what happens if I use 'gtk_set_transient_for to
mark it "modal to only one window"' under the hood.

Normally (as far as what I know), there is 1 gtk main thread listen
for all ui events (mouse click, resize etc). And when a moral dialog
is poped up, that main ui tread is blocked until user clicks OK or
Cancel (hence the window is frozen).

But for the case of 'gtk_set_transient_for ', how will that work? how
can 1 window is interactive when the Main UI thread is blocked by a
moral dialog in the 2nd window? (like the case in Firefox).

Thank you again.
