Move the dialog with a Hand

[Silvio]

the sample TestWScr.prg create a window with vertical and Horizontal scroll
can the user move the window with the mouse if click on window
I 'd like see a cursour hand and click on center and move the window as I click on the thumb of scrollbar....
Do U help me to create it ?

[Antonio Linares]

Silvio,

Here you have a working example:

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local oWnd, nRowPos, nColPos, lDrag := .F., oCrsHand

   DEFINE CURSOR oCrsHand HAND

   DEFINE WINDOW oWnd STYLE WS_POPUP COLOR "W/R"

   oWnd:bLClicked := { | nRow, nCol | nRowPos := nRow, nColPos := nCol, lDrag := .T., oWnd:oCursor := oCrsHand }
     
   oWnd:bMMoved = { | nRow, nCol | If( lDrag, oWnd:Move( oWnd:nTop + nRow - nRowPos,;
                                         oWnd:nLeft + nCol - nColPos ),) }  

   oWnd:bLButtonUp := { || lDrag := .F., oWnd:oCursor := nil }

   ACTIVATE WINDOW oWnd
     
return nil

Antonio,

When I run this sample I get a red rectangle that I can move by dragging it, but how can I close this?

Regards,
Marc

Marc,

Press Alt + F4

[Silvio]

Antonio,
I thinked to move the controls on a dialog and not move the position of the dialog

I explain you
see this image i use a dialog with style nOR( WS_CHILD, 4 )

the user can click on dialog and move the scroll position and see the other controls



If the user click on dialog with the mouse can move on the left or on the right or up and down and see the other control in this dialog
Now I can see all controls if I press on thumb of scroll


If I use the class TScrWnd with a Dialog I can use your commands also with a dialog style nOR( WS_CHILD, 4 ) ?

[Antonio Linares]

Silvio,

Use oControl:lDrag := .T.

that DATA is what it is set with the clause DESIGN

[Silvio]

perhaps U not understand me what I want make

type this...

oDlg:bLClicked := { | nRow, nCol | nRowPos := nRow, nColPos := nCol, lDrag := .T., oDlg:oCursor := oCrsHand }

oDlg:bMMoved = Set_SCROLL( oDlg,10 )



STATIC FUNCTION Set_SCROLL( oDlg,ntop )
LOCAL nStep := 30
oDlg:oVScroll:SetRange( 1, 10 )
oDlg:oVScroll:nPgStep = 1

oDlg:oVScroll:bGoUp = { || Move_controls( oDlg, nStep,ntop ) }
oDlg:oVScroll:bGoDown = { || Move_controls( oDlg, -nStep ,ntop) }
oDlg:oVScroll:bPageUp = { || Move_controls( oDlg, nStep ,ntop) }
oDlg:oVScroll:bPageDown = { || Move_controls( oDlg, -nStep,ntop ) }

oDlg:oHScroll:bGoUp = { || Move_controls( oDlg, nStep,ntop ) }
oDlg:oHScroll:bGoDown = { || Move_controls( oDlg, -nStep ,ntop) }
oDlg:oHScroll:bPageUp = { || Move_controls( oDlg, nStep ,ntop) }
oDlg:oHScroll:bPageDown = { || Move_controls( oDlg, -nStep,ntop ) }





RETURN NIL



STATIC FUNCTION Move_controls( oDlg, nStep,ntop )
LOCAL i
Local len:=len(oDlg:aControls )

IF nStep < 0 .AND. oDlg:aControls[len]:nTop + nStep = ntop
RETURN NIL
ENDIF
IF nStep > 0 .AND. oDlg:aControls[ 4 ]:nTop - nStep = ntop
RETURN NIL
ENDIF
FOR i = 2 TO LEN( oDlg:aControls )
oDlg:aControls[ i ]:Move( oDlg:aControls[ i ]:nTop + nStep, oDlg:aControls[ i ]:nLeft )

// Change from here
if oDlg:aControls[1]:nBottom + 60 > oDlg:aControls[i]:nTop
oDlg:aControls[i]:hide()
else
oDlg:aControls[i]:show()
endif
NEXT
oDlg:Refresh()
RETURN NIL

U can use too this...

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   public oWnd

   DEFINE DIALOG ownd  title "FiveWin - Move"
   ACTIVATE dialog oWnd centered ON LEFT  CLICK DRAGDLG( ownd )

return nil

STATIC FUNCTION DRAGDLG( oDlg )
    LOCAL aCoo := GETWNDRECT( oDlg:hWnd )
    LOCAL aOrg := GETCURSORPOS()
    LOCAL aPos, i
    WHILE GETKEYSTATE( VK_RBUTTON )
        aPos = GETCURSORPOS()
        oDlg:oCursor := oCrsHand
        MOVEWINDOW( oDlg:hWnd, aCoo[ 1 ] + aPos[ 1 ] - aOrg[ 1 ], aCoo[ 2 ] + aPos[ 2 ] - aOrg[ 2 ],,,.T.)
        FOR i = 1 TO 10
            SYSREFRESH()
        NEXT
    ENDDO
RETURN NIL

Dear Laiton,
perhaps U not undestand me
listen !!

I have a dialog ok ?
on this dialog I have many controls ok ?

then I have a vertical and a Horizontal scrollbar but I not want use they for scroll the dialog

If I click on background of this dialog the procedure shoe a cursor hand and I can scroll the dialog where I want : if I move the mouse on left or an right ( or up and down)
I can see all controls are moved

Imagine
you have a pdf into your screen : you can click on this pdf and move the page up and down left and right : you not move the window but U move what is write on this page

do U understand what I want make ?

[lailton.webmaster]

I can understand more.. sorry i can´t help
think that Antonio is people that know how make it...

i think that you need use "acontrols:lDrag := .T." but o don´t meet very think about it.

thanks

[Otto]

Hello Silvio,

I had a look into testwscr.prg.

I think you need a kind of PAN functionality.

I tried with the code I attached I think this could work. Press down the wheel - like in AutoCad - and then move the mouse.
Please post back your code changes if you have success.


Best regards,
Otto
