Thread: menus and opengl

hi, i have an opengl app in a window with a menu and i have 2 problems.
1. when i click a menu option and a pop up dialog box appears, the app freezes completely. now if i move this dialog box around the screen, the area of the app becomes blured with this box and looks really ugly. this means the GL loop does not refresh itself. how can i make it refresh when the dialog box is open?
2. i've made it so that when a user presses enter the game begins, the problem is that if the pop up dialog box is open and the user pressed enter to quit that dialog box, the game starts. this means that the GetAsyncKeyState() function catches this keyboard message and the app thinks that the user wants to start the game when he's really just closing the dialog box. how can i make it ignore the keyboard messages if a menu dialog box is open?

1. How are you creating the dialog?

Sounds like it is modal not modeless.

Could send the OpenGL window an update/paint msg each time a msg flows through the popup dialogs callback, but this may create other issues (depending on what the dialog is for).

Dante Shamest, yes, i guess the bool flag way would be the easiest to do. about WM_KEYDOWN, i've heard it's slow and it's better to use GetAsyncKeyState.

novacain, i create a dialog box with DialogBox(GetModuleHandle(NULL), ..).

>>i create a dialog box with DialogBox(GetModuleHandle(NULL), ..).

Try CreateDialog()

DialogBox is modal, control is not returned to the app until the dlg closes.

CreateDialog() is modeless, so msgs can flow through the app while the dlg is open.

cool, i didn't know such function existed, thanks. it worked, but i had to use WS_VISIBLE in my resource file for it to work, hope this is the right way to do it.
