Noesis 2.1.0.b14 C++ with GLFW problem with ComboBox
I am porting my unfinished program in to 2.1.0b14 and I have problem with ComboBox. If I click on it, GUI rendering freeze, but looks like "logic" is still working because I can close program or do something, but I don't see it visually because GUI is not updated.
Another problem, and I think this produce the problem, is SelectedIndex. When I open option window(from my program) in codebehind it take value from SelectedIndex and when this is called, program crash.
I use GLFW (OpenGL) and I followed IntegrationGLUT sample for my program. Btw. program run ok, except ComboBox.

Code: Select all
int32_t ContainerItem::m_func_GetSelectedIndex() const // int32_t was previously NsInt32 which is non existent in Noesis 2.1.0.b14
{
return m_i32_SelectedIndex;
}
/// -------------------------------------------------------------------------------------------------------------------
void ContainerItem::m_func_SetSelectedIndex(const int32_t index)
{
m_i32_SelectedIndex = index;
switch (m_i32_SelectedIndex)
{
// ...
}
Changed(NSS(ContainerItem_SelectedIndex));
}

This seems like a problem with offscreens. You have to make sure that your main frame buffer is restored after IRenderer::RenderOffscreen is called as you can see in our basic integration sample:
Code: Select all
void DisplayFunc(void)
{
#ifdef NOESIS_GUI
// Update view (layout, animations, ...)
_view->Update(glutGet(GLUT_ELAPSED_TIME) / 1000.0);
// Offscreen rendering phase populates textures needed by the on-screen rendering
_view->GetRenderer()->UpdateRenderTree();
_view->GetRenderer()->RenderOffscreen();
#endif
// If you are going to render here with your own engine you need to restore the GPU state
// because noesis changes it. The framebuffer and viewport are restored here
glBindFramebuffer(GL_FRAMEBUFFER, 0);
glViewport(0, 0, glutGet(GLUT_WINDOW_WIDTH), glutGet(GLUT_WINDOW_HEIGHT));
glClearColor(0.0f, 0.0f, 0.25f, 0.0f);
glClearStencil(0);
glClear(GL_COLOR_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
#ifdef NOESIS_GUI
// Rendering is done in the active framebuffer
_view->GetRenderer()->Render();
#endif
glutSwapBuffers();
glutPostRedisplay();
}

Aha, I didn't have this: glBindFramebuffer(GL_FRAMEBUFFER, 0); after that no problems, but I need use glew, which is now working with Noesis.
