Yep that's right, another update.  Redownload and install from the link provided with yout purchase.

Changes/Additions:
--------------------------
- Partial GUI functionality.
- 'window' class added. -- See 'gui.inc' in your BIN directory
:: can be used to resolve the scope of a function - discussed earlier
!! is used to call a base class function from a derived virtual one.  As in :

window !! WndProc(message,lparam,wparam)

- The space was removed from STR$ output.
- virtual functions are now working properly
- Many parser lockups fixed
- Sample 'window1.src' added

Have to go pick up my kids....be back with more details in a while.

Yay!!  :D
Thanks a lot! I'm going to have fun with this

Zen

Woo Hoo. Now the real fun starts.

Thanks a lot Paul.

Probably me being stupid again but ive just tried to make a program with the new GUI update. I wanted to make a message box when the user click the close button but i dont know what to put as the first argument because in the class definition it doesnt actually have the class variable used to create the window (if that makes sense).

Zen

Yes of course it was me! The missing link was "this"

You can either use the GetHandle() method or just use the m_hWnd variable. If you remember in IBasic, we had to use window.hWnd when calling API functions. It's pretty much the same thing here.

Updated again.  Fixed the bug that lewis found ;)

Sorry to make you redownload twice in as many hours.

Thanks Paul.

Its ok i dont mind downloading again. At least its only 2mb.

Current methods available in the window class.  Documented here for those that don't want to keep looking in "gui.inc"


//graphics
declare BackPen(unsigned int crColor);
declare Circle(int x, int y, int r, OPT unsigned int outline=0xFFFFFFFF, OPT unsigned int fill=0xFFFFFFFF);

declare ShowWindow(nCmdShow as INT,OPT id=0 as INT);
declare StartTimer(unsigned int time,opt int nIDEvent=1,opt unsigned int callback);
declare StopTimer(opt int nIDEvent=1);


Current message handlers overridable from the window class


//message handlers
declare virtual OnChar(unsigned int nChar,INT nRepCnt);
declare virtual OnClose(),int;
declare virtual OnCreate(),int;
declare virtual OnDestroy(),int;
declare virtual OnKeyDown(unsigned int nChar, INT nRepCnt, unsigned int nFlags),int;
declare virtual OnKeyUp(unsigned int nChar, INT nRepCnt, unsigned int nFlags),int;
declare virtual OnLButtonDown(int x,int y, int flags),int;
declare virtual OnLButtonUp(int x,int y,int flags),int;
declare virtual OnLButtonDblClk(int x,int y,int flags),int;
declare virtual OnMouseMove(int x,int y,int flags),int;
declare virtual OnPaint(),int;
declare virtual OnRButtonDown(int x,int y,int flags),int;
declare virtual OnRButtonUp(int x,int y,int flags),int;
declare virtual OnRButtonDblClk(int x,int y,int flags),int;
declare virtual OnSize(int nType,int cx,int cy),int;
declare virtual OnSizing(int nSide,RECT rc),int;
declare virtual OnTimer(int nIDEvent),int;


There will be another update this evening with more message handlers.  Override WndProc if you need to process an unhandled message before then.  Just don't forget to call the base class implimentation.

Other functions that crept into this release:


//functions
declare extern ColorRequest(window *win,OPT unsigned int initcolor=0xFFFFFF),unsigned int;
declare extern FontRequest(window win,int vSize BYREF,int vWeight BYREF,unsigned int vFlags BYREF,unsigned int vColor BYREF,OPT string name),HEAP;
declare extern MessageBox(window *win,string text,string caption,OPT unsigned int flags),int;
declare extern WAIT(OPT int nosleep=0);
declare extern RGB(int r,int g,int b),unsigned int;


FileRequest was also changed to accept a window class as the parent parameter.

Just wondering, will it be possible eventually to do this:
OnCommand(WM_NCLBUTTONUP, &MyProc);
...
sub MyProc(UINT msg, WPARAM wParam, LPARAM lParam)
{
...
}

assuming we have windows headers translated

Ionic Wind Support Team

OnCommand will be an overridable in the next update.  No need for an external function.

Also don't forget you can override WndProc now in any derived class to get ahold of any available message before it gets sent to the virtual handlers.

Can i have an example of using the hWnd because i tried to use it to listen for a message but it froze my program ???

Lewis

??

Do you mean overriding WndProc?

Open the 'window1.src' example, uncomment the mywindow::WndProc function and the declaration in the mywindow class.


class mywindow : window
{
//overridden functions.
declare OnClose(),int;
declare OnCreate(),int;
declare OnTimer(int nIDEvent),int;
declare WndProc(unsigned int message, unsigned int wparam, unsigned int lparam),int;
}




mywindow::WndProc(unsigned int message, unsigned int wparam, unsigned int lparam),int
{

        select(message)
        {
             case WM_COMMAND:
                //do something
        }
         //call the base class
return window!!WndProc(message,wparam,lparam);
}

Yes sorry, i meant overriding it.

I dont know what i did wrong exactly but now i know how to do it.

Thanks a lot.
