XBROWSE Border on cells

[byte-one]

Mr. Nages, can i draw a border with a specific color and width around a cell but only on cells with edit-functions (get, listbox, etc.)

[nageswaragunupudi]

You need to use oCol:bPaintText and paint the text and border of the cells the way you want.

[byte-one]

Mr. Rao, can you please provide a sample, that show only the border different to the normal view (Text, Data,..) of the cell.

[ukoenig]

Günther,

still a solution needed

You need to use oCol:bPaintText and paint the text and border of the cells the way you want.

A border around each cell or only around the column
( uses different colours as well on age ranges )

Uwe, I use a adapted version from class xbrowse. But i must every new FWH adapting new. The border with specific width and color are shown only on edit-cells and can differ any column.

[ukoenig]

Günther ,

The border with specific width and color are shown only on edit-cells
and can differ any column.

if it is the solution You are looking for -> different colors and pensize I will provide the code.
I think a border of the complete column ( edit ) is needed ?

Only functions are used, NO change of xBrowse.prg is needed :
COL_RECT( oBrw, hDC, 2, 255, 3, .F. ) // column-number, pencolor, pensize, lData
It is done using GDIPLUS, doesn't use < oCol:bPaintText >
If lData = .T. the border starts and ends with the data-area, header and footer are not included.
You can adjust the top and bottom-line ( make them not visible if needed )

Uwe, i will show the border only around the actual cell to edit and only if this cell has focus!

[ukoenig]

Günther,

I tested painting a border on a defined cell.

The function will include 3 solutions

1. border on column with only data-area
2. border on column with header and footer
3. border on focused cell

i will show the border only around the actual cell to edit and only if this cell has focus!

I still need the status got- and lost-focus of the cell to draw or delete the border.
Painting and deleting cell-borders is working .

for a selected cell something like:

:bGotfocus := {|nRow, nCol|...
:bLostfocus := {|nRow, nCol|...

or is it possible to use :

METHOD GotFocus( hCtlFocus ) INLINE ( ::oActive := Self, ::Super:GotFocus( hCtlFocus ),;
If( GetParent( hCtlFocus ) != ::hWnd, ::Super:Refresh( .f. ),) )

METHOD LostFocus( hCtlFocus ) INLINE ( ::Super:LostFocus( hCtlFocus ),;
If( GetParent( hCtlFocus ) != ::hWnd, ::Super:Refresh( .f. ), ) )

Finished

added to a existing sample

Autofocus on first column
Border deleted loosing the focus
You can use rounded as well or changing the bordercolor and pensize



You can download the complete source and running exe

maybe You must delete this line :

oBrw:lHoverSelect := .T. // autofocus

Code: Select all

#include "fivewin.ch"

STATIC lDel := .F., nColRow := 1

FUNCTION MAIN()
local oWnd, oBrw, oFont, oBold

USE WWONDERS NEW

DEFINE FONT oFont NAME "TAHOMA"  SIZE 0,-12

DEFINE WINDOW oWnd TITLE "Image and Text in same cell"
oWnd:SetFont( oFont )

@ 0,0 XBROWSE oBrw OF oWnd DATASOURCE "WWONDERS" ;

oWnd:oClient   := oBrw

oWnd:nHeight   := 700

oBrw:bPainted := < |hDC|   
  // CELL_BORDER( oBrw, hDC, nColumn, nRow, nRGBColor, nCellPen, lDel )
      CELL_BORDER( oBrw, hDC, 1, nColRow, 255, 10, lDel )

A extended test :

For the test You need the new :

oBrw:lHoverSelect := .T. // autofocus

1. using multiple columns
2. different forms and colors for each column
3. select if You want to show a border only on focused cell or all defined edit-cells on row-focus

Uwe, thank you!!! I will test and report.

[ukoenig]

Günther,

I hope it will work for You
I think I will create a little painter with a source-generator.

testing glowing borders



Another question :
did You try to compile < TGDIPLUS.cpp >
For any reason I don't get it working.
I want to test the new texture-brush - solution.
Maybe You have a link sample ?

Uwe

Uwe, maybe you have not switched the compiler to C++! Add the switch -P to your compiler. (Borland)

[ukoenig]

Günther,

# maybe you have not switched the compiler to C++!
# Add the switch -P to your compiler. (Borland)

Yes it is missing

IF EXIST MAIN.res echo MAIN.res >> b32.bc
$(BCDIR)\bin\ilink32 -Gn -aa -Tpe -s -v @b32.bc
Günther,

# $(BCDIR)\bin\ilink32 -Gn -aa -Tpe -s @b32.bc
del b32.bc

.PRG.OBJ:
$(HBDIR)\bin\harbour $< /N /W /Oobj\ /I$(FWDIR)\include;$(HBDIR)\include > clip.log
$(BCDIR)\bin\bcc32 -c -tWM -I$(HBDIR)\include -oobj\$& obj\$&.c

.C.OBJ:
echo -c -tWM -D__HARBOUR__ -DHB_API_MACROS > tmp
echo -I$(HBDIR)\include;$(FWDIR)\include >> tmp
$(BCDIR)\bin\bcc32 -oobj\$& @tmp $&.c
del tmp

MAIN.res : MAIN.rc
$(BCDIR)\bin\brc32.exe -r MAIN.rc

Just tested and works

Uwe

[ukoenig]

Günther,

I created a new example to test any combination.
Some improvements are done to reduce the code-size

1. solid line or glow
2. position : outside cell, covering celllines or inside
3. a possible transparent level
4. corners rounded if selected
5. different pensizes

Uwe
