ive been looking at DGSDK for a while now because ive loved using DB and DBP. downloaded the samples and checked them out, but have some questions about when its in windowed mode.

1) is there a way to remove controls (minimize/maximize buttons)
2) restrict resizing the window

im taking a shot in the dark, but does the DGSDK have commands to do this, or is this something that will have to be done with some other C++ commands?

another thing, if there is a way to allow rezising the window but have it keep a 1 for 1 pixel ratio... meaning not have it stretch or shrink the rendered image to fit the resized window?

I think you would need to subclass the window and handle the window resizing there. In addition you can also change the window layout.

dbSetWindowLayout(0, 0, 0);

This gives you:
- no icons in the top/right
- no title bar
- default windows icon

Removing the icons from the top/right makes the window non-resizable.

In non-fullscreen windowed mode, the window is always 1-to-1 with the desktop [edit] unless you resize it. If you want to maintain this as the window is resized, you can reset the resolution to the window size each frame (subclassing, or just grabbing the window size yourself) [/edit]

with that command can you still have the min/max/close icons but just not resize? just like throwing out questions before i drop the $180 on DarkSDK

off-topic question as well, can you rename functions in the header files and still have everything work? like renaming dbMaximiseWindow to dbMaximizeWindow (dont know if that is actually a command, but i know some commands are spelled different than first goes through my head)

Resizing - you'll probably need to subclass the window like BB originally said

Renaming - no ... and yes.
You can't change the header file, but you can create an inline function or a define to effectively do the same thing:

+ Code Snippet

inline void dbMaximizeWindow() { dbMaximiseWindow(); }

// or

#define dbMaximizeWindow dbMaximiseWindow

not that familiar with sub-classing, but would it also sub-classing i would have to use if i wanted DarkSDK to render to a part of a window that is already there? or is this not possible using DarkSDK?

i.e. using a resource file that has a window (form) with windows controls, and just an area of that window is actually DarkSDK, like you would see in a level editor or something (would use the commercial version of DarkSDK because the licence allows you to create anything

)

I use the following in my AtomZ puzzle game (http://homepages.nildram.co.uk/~nickk) to sub-class the window :

+ Code Snippet

wpOrigEditProc = (WNDPROC) SetWindowLong(g_pGlob->hWnd, 
												GWL_WNDPROC, (LONG) EditSubclassProc);

With EditSubclassProc handling all the Windows messages

LRESULT APIENTRY EditSubclassProc(HWND hwnd, 
									UINT uMsg, 
									WPARAM wParam, 
									LPARAM lParam) 
{
	switch (uMsg) {
		case	WM_NCHITTEST	:	{
									register int x = LOWORD(lParam);
									register int y = HIWORD(lParam);
									RECT wr;

GetWindowRect(hwnd, &wr);

x -= wr.left;
										y -= wr.top;
										if (y <= GetSystemMetrics(SM_CYFRAME)) 
										{
											if (dbSpriteVisible(loadData[INDEX_POINTER].idNum))
											{
												dbHideSprite(loadData[INDEX_POINTER].idNum);
												dbShowMouse();
											}										
										}
										else 
										if (y <= (GetSystemMetrics(SM_CYFRAME) + GetSystemMetrics(SM_CYSIZE))) 
										{
											if (x >= 6 && x <= 19 && y >= 6 && y <= 19)
											{
												if (dbSpriteVisible(loadData[INDEX_POINTER].idNum))
												{
													dbHideSprite(loadData[INDEX_POINTER].idNum);

												}												//return HTCLOSE;
											}
											else
											{

												{
													dbHideSprite(loadData[INDEX_POINTER].idNum);
													dbShowMouse();
												}
												//return HTCAPTION;
											}
