I.e. whenever a 'Skip Refresh' button is shown, it is never busy with something else. In contrast the code which leads to this bug is like: -------------------------------------------------------------------- `PushButton( `id(`foo), _("Foo") ) .. DoSomethingWhichMayTakeUnexpectedlyMuchTime(); .. symbol ui = (symbol) UI::UserInput(); -------------------------------------------------------------------- As long as it is in the DoSomethingWhichMayTakeUnexpectedlyMuchTime function, it will not respond to a click on [Foo]. When the author knows it may take much time the code is: -------------------------------------------------------------------- `PushButton( `id(`foo), _("Foo") ) .. Popup::ShowFeedback( _("Doing Foo. Please wait...") ); DoSomethingWhichIsKnownThatItMayTakeMuchTime(); sleep( 1000 ); Popup::ClearFeedback(); .. symbol ui = (symbol) UI::UserInput(); -------------------------------------------------------------------- When the author knows it takes much time in any case the code is: -------------------------------------------------------------------- `PushButton( `id(`foo), _("Foo") ) .. Popup::ShowFeedback( _("Doing Foo. Please wait...") ); DoSomethingWhichIsKnownToTakeMuchTime(); Popup::ClearFeedback(); .. symbol ui = (symbol) UI::UserInput(); -------------------------------------------------------------------- But a code like -------------------------------------------------------------------- `PushButton( `id(`interrupt), _("Interrupt") ) .. DoSomethingWhichIsKnownThatItMayTakeMuchTime(); .. if( `interrupt == (symbol) UI::UserInput() ) exit; -------------------------------------------------------------------- cannot work because clicking [Interrupt] is ignored until DoSomethingWhichIsKnownThatItMayTakeMuchTime had actually finished. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
