Why own IOSDPlgWindow is rendered repeatedly?

[SnoopyDog]

Hi

 

Currently i'm trying to create an own OSD window. Basically i succeeded, but there is a big problem for me:

 

My new window has a transparent background. If i show it in the OSD, it is not only rendered the first time it shows up on the OSD - no, there seems to be a timer running which renders it on and on. And with the time, the transparent background gets black!

 

If i open a standard OSD window like the "dialogInfo.xml" this does not happen!

 

How can i prevent my own window from getting rendered on and on automatically?

 

This is how i create the window:

VAR Something: IUnknown;
....
OSDWindowManager.NewWindow(MY_WIN_ID,'myWin.xml',Self,-1,'','','','-','','','',0,FALSE,Something);

 

And this is how i show it on the OSD:

OSDWindowManager.ActivateWindow(MY_WIN_ID);

 

Any help or hints would be VERY welcome!

You mean to say: the OSD does not get cleared before rendering.

 

Please show the myWin.xml

First i've made a copy from the original "dialogInfo.xml" and used it. When i open this xml file with the standard Info dialog in (e.g.) the channel list (myChannels.xml) it also does not seem to clear the OSD (?) because it overlays the previous OSD screen. But it does not get rendered on and on.

 

I attached the xml and pics that i'm trying to use.

 

It's 1:1 the same like the standard info dialog that i use in my skin

In the plugininterface please check if the following is there:

 

function TBaseOSDPlugin.OnDoesRender(const Window : IOSDPlgWindow;Layer :
Integer): HRESULT;
begin
 if (Window.RenderLayer = Layer) and Window.visible then 
result:=s_OK 
 else 
Result:=E_FAIL; 
end;

If not please add it.

Your doing a overlay window (like a dialog) or a standalone window (which doesn't gets rendered on top of another window)?

[SnoopyDog]

Yes, i try to.

 

And i will add the code fragment that you've posted cause it's missing currently. Maybe this helps already

[Lars_MQ]

allowoverlay="true"

Make it a false. Otherwise it means: this window uses a small TV window.

[Lars_MQ]

Yes, i try to.

Well my question was not a True/False question. So: Dialog or Standalone?

[SnoopyDog]

The code (OnDoesRender) does not help.

 

If i set "allowoverlay" to false the the screen gets totally black. I want to use the overlay from the previous screen, this is why i set it to "true". And with the normal "info" dialog, the same XML file works without any problem. Don't know what goes wrong.

 

Edit: Uuups - i'm trying to create an overlay window that should be used like a dialog

Oh you can't do real dialog windows, only an overlay (like the volume display, not selectable and non blocking). Own Dialogs are not covered by the PluginSDK.

 

Sorry my last question was misleading, I should have asked Overlay or standalone...

[SnoopyDog]

O.k. thank you for the answer.

 

No problem - i'll try a "trick" to get something similar work... Will see...
