*-* =====================
void UpdateWindow(int mode)
Update display.
mode : (1) update
(0) sync
Int_t WriteGIF(char *name)
Writes the current active window into pixmap file.
The format is defined by the file name extension
like "png","jpg","bmp" . . .
If no extension is provided the "png" format is used by default
Returns 1 in case of success,
0 otherwise
Note: this method may not produce the expected result been called
---- from the ROOT prompt by simple reason:
The active window will be console window
rather the last selected ROOT canvas.
void WritePixmap(int wid, UInt_t w, UInt_t h, char *pxname)
Write the pixmap wid in the bitmap file pxname in JPEG.
wid : Pixmap address
w,h : Width and height of the pixmap.
if w = h = -1 the size of the pimxap is equal the size the wid size
pxname : pixmap file name
The format is defined by the file name extension
like "png","jpg","bmp" . . .
If no or some unknown extension is provided then
the "png" format is used by default
Int_t LoadQt(const char *shareLibFileName)
Make sure we load the GUI DLL from the gui thread
Int_t processQtEvents(Int_t maxtime)
Force processing the Qt events only without entering the ROOT event loop
