Curious about absent Maximize application function.

[enablerbr]

I noticed there is no command to utilize the Maximize button on a graphic window. Is there any reason for this?

[Masterxilo]

The blitzmax graphics window creation method doesn't add this since this feature is OS specific. But you can easily add it yourself once you have the handle to le's window using:

SetWindowLong(m_hWnd, GWL_STYLE, GetWindowLong(m_hWnd,GWL_STYLE)|WS_MINIMIZEBOX|WS_MAXIMIZEBOX); 

(This also adds a minimize button, m_hWnd is the handle to LE's window which you can get using, for example, FindWindow)

i use c#. so i'll have to look into it further. thanks.

The commands Masterxilo illustrated (FindWindow and SetWindowLong) are Windows API commands and not language specific so you just need to call these from C#.

[enablerbr]

           hWnd = WindowsAPI.FindWindow("DFTester.exe", null);
           WindowsAPI.SetWindowLong(hWnd, WindowsAPI.GWL_STYLE, WindowsAPI.GetWindowLong(hWnd, WindowsAPI.GWL_STYLE) | WindowsAPI.WS_MAXIMIZEBOX);

 

as i don't understand the use of FindWindow. is that the way it shoud be used? or should "DFTester.exe" be replaced with something else?

also would i put this before Graphics() or after it?

[Masterxilo]

After it. And you should create your window with an unique title (at least, it has to be set since you need to know it afterwards).

The syntax of find window is classname (you don't need that -> null), window title/caption (not executable file name ).

 

So the process of getting the window handle is:

SetAppTitle("MY APPLICATION");
Graphics(...);
hwnd = FindWindow(NULL, "MY APPLICATION");

thanks Masterxilo. now it works. though as i suspected. the backbuffer doesn't change to match. guess thats why it was left out. so i can only use it with my own OpenGL context.

[Masterxilo]

It works with the default window, it's just kinda "hacky".

 

You could retrieve the size of the maximized window once it gets maximized (you'll need to hook to the windows message callbacks to find out when this happens).

You can then call Graphics() again with the new size and then maximize that new window yourself (maximizing this window won't make it's backbuffer too small, since you already gave it the correct size).

[enablerbr]

if i call Graphics() again won't it just start a new window?

 

scratch that. i just did a test and it does just start a fresh window and without the Maximize button.

 

this has just made me realise that without the LE ability to natively resize a graphics window. everytime a user decides they need to change resolution. the app has to be restarted from fresh. which i guess is the same for changing from a window state to a fullscreen state.

[Masterxilo]

everytime a user decides they need to change resolution. the app has to be restarted from fresh

? No it doesn't, you just have to call Graphics() again, no restarting/reloading required.

           hWnd = WindowsAPI.FindWindow("DFTester.exe", null);
           WindowsAPI.SetWindowLong(hWnd, WindowsAPI.GWL_STYLE, WindowsAPI.GetWindowLong(hWnd, WindowsAPI.GWL_STYLE) | WindowsAPI.WS_MAXIMIZEBOX);

Hi,

 

use this :

	HWND hwnd =FindWindow("BlitzMax GLGraphics",AppTitle);
	ShowWindow(hwnd,SW_SHOWMAXIMIZED);

 

AppTile is the name by default is "" or use SetAppTitle( AppTitle ) ; befor Graphics(..,..);

 

;-)

If you use terrain, then you have to restart the application, because changing window size makes the terrain flat. However, since you can use Sculptris 3D terrain, you can resize on the fly also.

Mmm, built-in Sculptris terrain... That would be killer.
