我有一個問題,我使用過量(openGL實用程序工具包)。我正在一個主窗口中創建一個子窗口。主窗口顯示一個簡單的圖形,子窗口顯示另一個視圖的圖形。該圖旋轉,因此應始終重新顯示主窗口和子窗口。OpenGL子窗口不會同時響應
但是隻有一個顯示旋轉圖。因此,當我啓動程序時,主窗口中的圖形旋轉,但在子窗口中不旋轉,它只是靜止不動。
當我在子窗口中移動鼠標並按任意鍵時,角色發生變化,圖形在子窗口中旋轉,並在主窗口中靜止。
我該如何讓它們同時顯示。我跟着燈塔的教程,但沒有給我答案。 我必須對我的視口做些什麼嗎?
* GLUT Shapes Demo
*
* Written by Nigel Stewart November 2003
*
* This program is test harness for the sphere, cone
* and torus shapes in GLUT.
*
* Spinning wireframe and smooth shaded shapes are
* displayed until the ESC or q key is pressed. The
* number of geometry stacks and slices can be adjusted
* using the + and - keys.
