When i move sdl window the app freeze...

[arthurprs]

When i move sdl window or the console window the app freeze... :? It's a problem on the code or what ?

[pascal]
program onMines;

{$APPTYPE CONSOLE}

uses
SysUtils,
SDL,
const_unit,
type_unit;

var
screen: PSDL_Surface;
ltick: Cardinal;
event: TSDL_Event;

const
fps = Trunc(1000 / 30);

begin
SDL_Init(SDL_INIT_VIDEO);
screen := SDL_SetVideoMode(640, 480, 24, SDL_SWSURFACE or SDL_DOUBLEBUF);
while True do
begin
ltick := SDL_GetTicks;
SDL_PollEvent(@event);
case event.type_ of
SDL_MOUSEMOTION:
Writeln(Format('mouse moved to x:%s | y:%s',[IntToStr(event.motion.x), IntToStr(event.motion.y)]));
SDL_KEYDOWN:
Writeln(Format('tecla : %s foi pressionada',[IntToStr(event.key.keysym.scancode)]) );
SDL_QUITEV:
Break;
end;
SDL_Delay(fps - (SDL_GetTicks - ltick));
end;
SDL_Quit;


end.
[/pascal]


and,
how can i have the console window to make only sdl window visible?

Edit: one more question, in that code when i press "A" it recognizes many many A presses

Hi

I have noticed that when moving an SDL window about the app freezes , I think this happens in most SDL apps. It's just something that happens (please someone correct me )

You can get rid of the Console window by removing the line

[pascal]
{$APPTYPE CONSOLE}
[/pascal]

This can be handy sometimes so I tend to use

[pascal]
{$IFOPT D+}
{$APPTYPE CONSOLE}
{$ENDIF}
[/pascal]

Which just enables the console window when debugging is enabled.

To stop the same key being handled you have to either

1) use SDL_EnableKeyRepeat to disable key repeat
2) use SDL_GetKeyState to get the current state of the keyboard then check if the key is pressed. (See Demos in JEDI-SDLv1.0 to examples)

Hope this helps

Thanks xD

but the sdl window freezing is much bad =/

[jasonf]

I've never noticed this.. (Sorry if this seems to contradict you Technomage)

Could you please post an example of the freezing app so I can test it? I'm a little worried that this might be an SDL issue which I'm not aware of using a different hardware setup to my own.

I get the same thing as Dean. Actually what happens is that while the window is being dragged the program will freeze for that time. Let go of the mouse button to stop dragging it and the program will resume.

I believe it has to do with SDL's window management specifics.

my english don't able me to understand if you proposed an solution or not ops:

can you rewrite it ?

sorry

I'm trying to say that your problem is normal. SDL does that.

[arthurprs]

I'm trying to say that your problem is normal. SDL does that.

But it Freezes completly :? , it don't recover... it crashes..

its normal :shock: ?

Edit: its possible to create a surface based on a bitmap on memory ?

[WILL]

Well, crashing like that is not normal... :?

I think you might be either doing something wrong/unconventional(not normal) in your code or you something might be corrupt somewhere...


When you create a SDL_Surface thats basically what you're doing. You're making achunk of memory that is the actual color data. You just have to know what pixel format you want to use and stick to it.
