window:center() doesn´t work right

[AHF]

Yes. The first mdichild is centered. How can I use it?

[Antonio Linares]

Do you want to center all of them ?

Please explain a little what you want to do, thanks

[AHF]

Antonio,

I need that the ::center() method on mdichilds places them in the center of the main window.

Antonio,

I need that windows are centered in order that all the mdichild is automacticly visible otherwise the user will have to center the window by hand to begin toi work. The Mdichilds can't be maximized or chanhed in size.

Antonio,

Have you tried to use this code:

Code: Select all  Expand view

function BuildChild( oWnd )

   local oChild

   DEFINE WINDOW oChild TITLE "Test" MDICHILD

   WndTop( oChild:hWnd, 30 )  // change 30 for your own needs
   WndLeft( oChild:hWnd, 30 )  //    "

return nil

Excellent!

Will you mind to share the code with us ? thanks!

[AHF]

Antonio,

Right! Here it is :

METHOD Center() CLASS TDMdiChild //own class redefinition
LOCAL nLargura,nAltura,ntop,nleft
LOCAL nlrgmain,naltmain
LOCAL meioljan, meiolmain,meioajan,meioamain

nlargura := ::nwidth() //dialog width
naltura := ::nheight() //dialog height

nlrgmain := Wmain():owndclient:nwidth() //container width
naltmain := Wmain():owndclient:nheight()//container height

//middle of each dialog and container
meioljan := nlargura /2
meioajan := naltura /2
meiolmain := nlrgmain /2
meioamain := naltmain/2

//coordinates to place the mdichild
ntop := meioamain-meioajan
nleft := meiolmain-meioljan

WndTop( ::hWnd, ntop )
WndLeft( ::hWnd, nleft )
RETURN nil

Again problem.

If I modify the size of the main window the mdichilds opened after are disapering.

That is caused by my modify center() method posted before.

Ntop or Nleft are returning a negative value and when this happens the child window disapears.

Any ideas ?

Try using the main window's bResize codeblock to call the center function then maybe the mdichild Move() method (to redisplay it).

James,

It worked.

Thanks
