Lines and rectangles

[plantenkennis]

Hello
I can draw a line in a window or on paper using the next code:
@ nRow, nCol LINE HORIZONTAL SIZE oPrn:pageWidth() OF oPrn
But can I set the thickness of the line?

And is there also a code to draw a rectangle, in variations., like rounded corners, different lines (dotted, striped, full..)

[ellano]

Code: Select all | Expand

    DrawLine( oDlg1,270,540,250,540,0)
...

//---------------- Tracer une ligne entre 2 points avec une couleur définie -----//
Function DrawLine( oDlg1, xFrom, yFrom , xTo , yTo, nColor)
   LOCAL hPen, hOldPen
   LOCAL hDC1 := oDlg1:GetDC()

   hPen := CreatePen( 0, 2, nColor )   // largeur 2
   hOldPen := SelectObject( hDC1, hPen )

   MoveTo( hDC1, yFrom, xFrom )
   LineTo( hDC1, yTo,   xTo)

   SelectObject( hDC1, hOldPen )
   DeleteObject( hPen )
   oDlg1:ReleaseDc()

return NIL
 

If you meant in a report then:

Code: Select all | Expand

PrnLandscape()
PRINT oReport NAME "With lines" PREVIEW
DEFINE PEN oPen WIDTH 2 OF oReport
PAGE

nColumn:=oReport:nHorzRes()/132  && 132 columns
nRow:=oReport:nVertRes()/66 
oReport:LINE(7.5*nRow,5*nColumn,7.5*nRow,130*nColum,oPen)
ENDPAGE
ENDPRINT
oPen:END()
RELEASE ALL

René,

That code is for Windows. We will check for the OSX equivalent

René,

New Class TGroup Method SetBorderWidth( nWidth ):
https://bitbucket.org/fivetech/fivemac/commits/a392ba329772acc65c7009bb90a9bcfade9d3ca8
based on new function BoxSetBorderWidth():
https://bitbucket.org/fivetech/fivemac/commits/94fc9ace9ca38ee2fa10a5214c9505fa64faa485

Example of use:
@ nRow, nCol LINE HORIZONTAL oBox SIZE oPrn:pageWidth() OF oPrn
oBox:SetBorderWidth( 2.3 ) // any decimal value here

You may use:

oBox:SetBorderType( nType )

where nType is one of the following types:
https://developer.apple.com/documentation/appkit/nsbordertype

#define bezelBorder 2
#define grooveBorder 3
#define lineBorder 1
#define noBorder 0

For rounded corners it seems as we have to subclass from NSBox and override Method drawRect:

Hello Antonio,

The commands works perfect with GROUP command, but I don't see any changes WITH the LINE?
However, I can use a Group with height 5, that gives a thick line.

The rounded corners are not imporant for me, so if that gives problems at other places, we should not use it.

To make it work WITH in NSBox the box type must be NSBoxCustom = 4 .

See Testgrp.prg ....
Change :

@ 60 ,10 LINE HORIZONTAL oline SIZE 372 OF oDlg

to

@ 60, 10 GROUP oline SIZE 372, 5 OF oDlg
oline:setCustom()
oline:setBorderType(1)
oline:setBorderColor(0,255,0,100)
oline:SetBorderWidth( 5 )

anyway , @property NSBorderType borderType is deprecated and It's not advisable use custom lines in views.

Hello Mauel,

Thank you, this works perfectly for me. This programming tool is getting better every time. I love it.
