wxWidgets + opengl

[dualCat]

Hello,
I'm having a problem with my application, recently i have installed ubuntu and my work does not work on it. The problem is that, whenever i want to run my code, the openGL starts but it does not refresh itself (what i mean by that is - the cubes are not rotating). Only resizing will refresh the window(and rotate the cubes). Here is code for my app: link: wrzuc.net/get.php?what=f79vh3xyliengine.zip

I have added this code to test the cube rotations.

GLfloat	rtri=0;
GLfloat	rquad=0;
void liEngineGl::Render(void)
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);	// Clear Screen And Depth Buffer
	glLoadIdentity();									// Reset The Current Modelview Matrix
	glTranslatef(-1.5f,0.0f,-6.0f);						// Move Left 1.5 Units And Into The Screen 6.0
	glRotatef(rtri,0.0f,1.0f,0.0f);						// Rotate The Triangle On The Y axis ( NEW )
	glBegin(GL_TRIANGLES);								// Start Drawing A Triangle
		glColor3f(1.0f,0.0f,0.0f);						// Red
		glVertex3f( 0.0f, 1.0f, 0.0f);					// Top Of Triangle (Front)
		glColor3f(0.0f,1.0f,0.0f);						// Green
		glVertex3f(-1.0f,-1.0f, 1.0f);					// Left Of Triangle (Front)
		glColor3f(0.0f,0.0f,1.0f);						// Blue

I'm very frustrated right now, because i said 'no' to Vista, and decided to end my project on Linux, and now i really don't want to install that nightmare which Vista really is.

I'm on Ubuntu and i my laptop spec are

Manufacturer: Dell Inc.
Processor: Intel(R) Core(TM)2 Duo CPU T6400 @ 2.00GHz (2 CPUs), ~2.0GHz
Memory: 4054MB RAM

Unfortunately I'm not experienced with OpenGL, and my last work with wx was almost 10 years ago. However, I think that you are experiencing a buffering problem in that your changes have not been transmitted to the actual graphics engine. Is there an OpenGL or wxWidget funtion to refresh the display? If so, then try that after you have finished your updates to the "display".
