draw simple pixel in IGUIWindow

[Fk]

How can I do that? How can I draw graph, not static image, not texture, just simple pixel in my window(IGUIWindow)?
//I'm from Russia, so excuse me for my little english.
And I not want to create new driver for doing "driver->draw2DLine(x,y,x,y)" - I think it's not cool =\

I think you can view the code in Irrlicht source, may be the draw2Dline function to show how irrlicht draw a pixel...

Hope this helpul!

You could create yourself a texture and display that in the window and then edit the pixels of the texture as required. look at ITexture::lock()

ok, thanks, I thought that irrlicht should give me that chance to simple draw point, becouse it's so trivial! o_O =(

thanks, I'll try it

I'm curious how you intend to draw a graph with points instead of lines (unless you are doing a scatter plot) and make it cool. Most of the cool graphs are based on lines, bars or pies.

BTW, I wrote a line graph gui element a while back. I have it at home and I could post the code if you'd like.

I writing code that will output graph of my math function to IGUIWindow. And that graph must be resizeable as window by wheel.
=>window(IGUI)=>image=>texture
I recompiled engine. Window is resizeable by wheel now. And image too.

Code: Select all

if(event.EventType == EET_MOUSE_INPUT_EVENT && event.MouseInput.Event==EMIE_MOUSE_WHEEL) ViewGraph++;

Code: Select all

while(device->run()){
	driver->beginScene(true, true, video::SColor(0,100,100,100));
	if(ViewGraph>1) img->setRelativePosition(core::rect<s32>::rect(4,20,window->getAbsolutePosition().getWidth()-5,window->getAbsolutePosition().getHeight()-5));

Now I have problem with texture and her size. But I think I cope with it.
If you have a code help me, so write it, thanks. =)

Excuse me for my little english again.
