Resize a tpanel

[Silvio.Falconi]

if i have a tpanel in a window with controls is it possible to resize the tpanel
when i resize the window and still the same controls contained in the tpanel ?


I create the Panel with

Code: Select all  Expand view

 
#include "fivewin.ch"


function Main()
local oWnd,oPanel

DEFINE WINDOW oWnd
oPanel:= CreatePanel(oWnd,10,10,CLR_WHITE,CLR_HGRAY,200,200,.t.)
oPanel:bPainted := { || MyControls(oPanel) }


ACTIVATE WINDOW oWND
return nil
//-----------------------------------------------------------------------------//
Function CreatePanel(oWnd,nRow,nLeft,nColor1,nColor2,nBottom,nWidth,lBorder)
      local oPanel,oBrush
      local aGrad := { nColor1,nColor2}
      DEFAULT lBorder:=.f.
      DEFINE BRUSH oBrush GRADIENT aGrad

     oPanel:=Tpanel():New( nRow, nLeft, nBottom, nWidth, oWnd)
     oPanel:SetBrush( oBrush )
     IF lBorder
        oPanel:bPainted := { || oPanel:Box( 1,1,oPanel:nHeight-1,oPanel:nWidth-1 ) }
     Endif
     return oPanel
//-----------------------------------------------------------//
  Function MyControls(oPanel)
   local rc := GetClientRect(oPanel:hWnd)
   local hDc:=oPanel:getdc()
   local nTop     := rc[1]
   local nLeft    := rc[2]
   local nBottom  := rc[3]
   local nRight   := rc[4]
   LOCAL oFont := TFont():New("Tahoma" , 0, 40,, )
   Linea( hDc, nTop+48, nLeft+5, 0.5, nRight-11, CLR_HGRAY )
   PaintTEXT(nTop+60,nLeft,nBottom,nRight,hdc,"fivetech",CLR_RED,oFont)

   return nil
 //-----------------------------------------------------------//

static function Linea( hDC, nTop, nLeft, nBottom, nRight, nColor, nWidth )

   local hPen, hOldPen

   DEFAULT nColor := CLR_BLACK, nWidth := 1

   hPen = CreatePen( PS_SOLID, nWidth, nColor )
   hOldPen = SelectObject( hDC, hPen )

   MoveTo( hDC, nLeft, nTop )
   LineTo( hDC, nRight, nTop )

   SelectObject( hDC, hOldPen )
   DeleteObject( hPen )

return 0

Function PaintTEXT(nTop,nLeft,nBottom,nRight,hdc,ctext,ncolor1,oFont)
    local hFont, hOldFont
    local nOldMode,ncolor

    hFont    := oFont:hFont
    hOldFont := SelectObject( hDC, hFont )
    nOldMode := SetBkMode( hDC, 1 ) //transparent
    nColor   := SetTextColor( hDC, nColor1)

    nLeft +=  8

    DrawTextEx( hDC, cText , {nTop+2,nLeft,nBottom,nRight} )

    SetBkMode( hDC, nOldMode )
     SelectObject( hDC, hOldFont )
     SetTextColor( hDC, nColor   )
    DeleteObject( hFont )
    return nil

 

but on my application I use a tscrollpanel instead of the window

[nageswaragunupudi]

For ScrollPanel, please set RightMargin and BottomMargin, to make it resizable when container window/dialog is resized.
Sample:

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oWnd, oPanel, n

   DEFINE WINDOW oWnd

   oPanel := TScrollPanel():New( 20,20,100,100,oWnd )

   oPanel:nRightMargin  := 20
   oPanel:nBottomMargin := 20

   for n := 1 to 20
      @ n*20,20 SAY REPLICATE( Chr( n + 64 ), 20 ) SIZE 200,16 PIXEL OF oPanel
   next

   oPanel:SetRange()

   oWnd:nHeight   := 200
   oWnd:nWidth    := 200

   ACTIVATE WINDOW oWnd CENTERED

return nil

Dear Mr. Rao,
Thank you for this example.
Could you also please show how to make it horizontally scrollable at the same time?
Best regards,
Otto

We did not provide horizontal scrolling as of now.
We will look in to this and get back to you.

   oWnd:nHeight   := 200
   oWnd:nWidth    := 200

   ACTIVATE WINDOW oWnd CENTERED

Nages,
sorry i didn't mean that....

I have some panels inside a scrollpanel

the scrollpanel is inside a dialog which in turn is inside a window ( oWndMain)

when I resize the main window I perfectly resize the dialog and in turn also the scrollpanel it contains

the problem I have with the small panels that are inside the scrollpanel and the controls that are in each panel

Please see the video





I make a small simulation

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oWnd, oPanel, n

   local aPanel:=array(20)
   local nRow:= 1,nLeft:= 1
   local nColor1:= CLR_WHITE
   local nColor2:= rGb( 245,245,245)
   local nHeight := 20
   local nWidth
   DEFINE WINDOW oWnd

   oPanel := TScrollPanel():New( 20,20,100,100,oWnd )

   oPanel:nRightMargin  := 20
   oPanel:nBottomMargin := 20
   nWidth := oPanel:nWidth


    aPanel[1]:=CreatePanel(oPanel,nRow,nLeft,nColor1,nColor2,80,400,.t.)
    nRow+=80
    aPanel[2]:=CreatePanel(oPanel,nRow,nLeft,nColor1,nColor2,nRow+80,400,.t.)
     nRow+=80
    aPanel[3]:=CreatePanel(oPanel,nRow,nLeft,nColor1,nColor2,nRow+80,400,.t.)
    nRow+=80
    aPanel[4]:=CreatePanel(oPanel,nRow,nLeft,nColor1,nColor2,nRow+80,400,.t.)


    oPanel:SetRange()

   oWnd:nHeight   := 200
   oWnd:nWidth    := 200

   ACTIVATE WINDOW oWnd CENTERED

   return nil

 Function CreatePanel(oWnd,nRow,nLeft,nColor1,nColor2,nBottom,nWidth,lBorder)
      local oPanel,oBrush
      local aGrad := { nColor1,nColor2}
      DEFAULT lBorder:=.f.
      DEFINE BRUSH oBrush GRADIENT aGrad

     oPanel:=Tpanel():New( nRow, nLeft, nBottom, nWidth, oWnd)
     oPanel:SetBrush( oBrush )
     IF lBorder
     oPanel:bPainted := { || oPanel:Box( 1,1,oPanel:nHeight-1,oPanel:nWidth-1 ) }
     Endif
return oPanel



 

when i resize the scrollpanel i want the small panels to resize
