An ImagePanel is a vgui2 element defined in the vgui_controls library, in the file ImagePanel.cpp. ImagePanels are available in all source games. An ImagePanel is a simple panel that displays an image.
Before creating anything, we first need to include the ImagePanel header file and use the vgui namespace.
using namespace vgui;
ImagePanels can be created via the c++ keyword new with a simple call to ImagePanel:
ImagePanel* imagePanel = new ImagePanel(this, "myPanel");
Once we have our ImagePanel created, we can now tell it which image to display:
Its important to note that scheme::GetImage begins from "materials/vgui" and no extensions should be provided. So, scheme()->GetImage("vgui/eye", false) would really point to "materials/vgui/vgui/eye.vmt".
And we're done!
