hi,

i have a "filled" oDlg:drawingArea:Bitmap with a Picture.

now a have a Class FROM Thread placed on oDlg:drawingArea.
after some Time in :execute() each Thread will ::quit() and Thread
is still "alive" so i can "Re-Start" it within Class with ::start()

now before "Re-Start" i change Picture of oDlg:drawingArea:Bitmap
and need a oDlg:Configure() ... this raise CPU to 100 % !!!

Demo an more Information see
http://www.xbaseforum.de/viewtopic.php?f=32&t=4347

greetings by OHR
Jimmy

This class from thread is what exactly???

This part exists in another thread so can not see any events from the
host thread. Configure would send events to all its children  and this
part can not see the event because it runs in a different thread.

Why would you think this would work??

Jim

hi,

> Why would you think this would work??

sorry, when missunderstood :
if i do NOT use oDlg:Configure() in my ChangeBack() all work fine !

i need oDlg:Configure() when change oDlg:drawingArea:Bitmap, right ?
after this and "Re-Start" Thread it happend ONLY !

without oDlg:Configure() all Threads work fine with "Re-Start"
so i guess my Class FROM Thread (like Help Demo) is ok.

so why/how can a oDlg:configure() have Sideeffect on my Thread ?

hi,

got it !!!

to simulate BUG you need XP Manifest !!!
(else transparency work not well ...)

1.) put a Picture on oDlg:drawingArea:Bitmap

2.) have Class FROM Thread on oDlg:drawingArea

Class have only XbpStatic, but use { XBP_PP_BGCLR, -255  }
with Resource Picture on it.

3.) do a oDlg:Configure(), no need to change something

than all Class Thread will raise up CPU to 100%

!!!  Warning !!!

IF you have this Line :

>   oDlg:drawingArea:colorBG      := -255
