SDL packages [message #29807]

As commented in this post, there are new SDL and SCLCtrl_demo packages in Bazaar.

SDL contains SDLCtrl. It is the base for a MediaCtrl to come soon. However SDLCtrl will include a C++ interface to many SDL possibilities.

It includes also a SDLCtrl_demo, based in unodgs SDL demo. As it is in a Ctrl, it moves and resizes.

For now it is not documented, but I wanted to see people response before.

Ped has properly remember that SDL is LGPL. Because of it SDL sources are not compiled inside package (it would have been possible). Just to ease setup, SDL includes "plugin" folder containing includes, doc and the library for windows.

I do not think license is a problem, as a full installable would require to include LGPL and GPL contents like MinGW.

Hello all

SDLCtrl is really being a testbench for MediaCtrl...

Now I think it works well also in Linux, but the FullScreen mode that seems shifted. Could you test it?

Hello all

This is the problem with Fullscreen in Linux:
index.php?t=getfile&id=2943&private=0

The reason is that in SDLCtrl example, FullScreen().Run() is called from another TopWindow, so Fullscreen window is really opened under the main window. See this:

.FullScreen().Run();	--->

int  TopWindow::Run(bool appmodal)
{
...
	if(!IsOpen())
		Open();	--->


void TopWindow::Open()
{
	GuiLock __; 
	Open(GetActiveWindow());	--->
}


Ctrl *Ctrl::GetActiveWindow()
{
	GuiLock __;
	Ctrl *q = GetActiveCtrl();
	return q ? q->GetTopWindow() : NULL;
}

Doing for example Open(NULL); solves the problem. Or, is it necessary that GetActiveCtrl() call GetTopWindow() ?

Hi Koldo,

I tried you're SDL example in full screen and I don't have the problem you describe.
The buttons appear once the mouse is near the bottom.

But in the basic example, the displayed image doesn't seem correct to me, there is a sort of mix of the image with the background image.

What is the image suppose to look like
index.php?t=getfile&id=2944&private=0

Hello Didier

I use Ubuntu. What distro do you use?

About the image problem, I have seen it before and, analizing the picture, it seems a problem from the sample..., because the Black() is declared as transparent and in fact the background black is transparent.

Hi Koldo,

looking at the SDL.upp file, the SDL package currently depends on Core while when looking at the code, it seems that it should rather depend on CtrlLib... Can you fix that please?

Thanks a lot

Lionel
