Multiple Windows in same program with GTWVT

[Jayadev U]

Hi,

 

Please see this old post:

 

http://harbour.harbour-project.narkive.com/NI9z86v8/multi-window-gtwvt-first-implementation

 

I find references to Multiple Windows using GTWVT.  There are however missing functions which are not available in the post.  Link to source code is dead.

 

Question is, can we have multiple windows with GTWVT now ?, any examples ?

 

I know, I can have multiple windows with GTWVG or GTWVW.

 

Warm regards,

 

Jayadev

yes is possible using hb_gtCreate  hb_gtSelect()

With the function hb_gtCreate, create a new window using many gt gt. The function returns a pointer, which we will use the function hb_gtSelect,  To select this window as the current window.

Hi Massimo,

 

Many thanks for pointing me to the right direction.  I have since checked on Google for hb_gtcreate and also have downloaded the ‘Qalculator’.  Nice program.

 

I however, did not find any way to close an open window.  What is the command to close an open window ?

 

 

In the thread below, it says setting the variable to Nil will close the window.  I hope there is some more elegant way.

It also says in the thread that hb_gtRelease() is a C function,  how to send the pWin1 variable to the “C” function. (I am sorry, my “C” expertise is NIL).

/*Example for Multiple windows in GTWVT*/

FUNCTION GtNewWindow()

 

   LOCAL pGt1,pWin1 , pGt2 , pWin2

 

   pGt1 := hb_gtCreate( "WVT" )

   pWin1 := hb_gtSelect( pGt1 )

   pGt2 := hb_gtCreate( "WVT" )

   pWin2 := hb_gtSelect( pGt2 )

 

   CLS

 

   hb_gtSelect( pWin1 )

   WAIT "This is the 1st GT window. Press any key to close."

 

   hb_gtSelect( pWin2 )

   WAIT "This is a 2nd new GT window. Press any key to close."

 

Return NIL
