Also for Tree on the Xbrowse for Mr Rao

[Silvio]

Dear Mr. Rao,
After the last sample I try to insert another component but I think I must use another archive to insert the hardaware type because I have many component to insert :

Computer
Monitor
Keyboard
Mouse
Printer
Swicth
Scanner
Pocket
Camera
Projector

the code

Code: Select all  Expand view

function Main()

   local oWnd, oBrw ,oBold

as you can see on this picture



I add a code but I thinked perhaps there is another method or we can insert another dbf component.dbf ( code, description, images)





How I can make ?

Usage of HB_Decode:

Code: Select all  Expand view

             HB_DeCode( Trim(  oBrw:oTreeItem:cPrompt ), ;
                   'NOTEBOOK', 4, 'PRINTERS', 5, 'MONITOR', 6, 'KEYBOARD', 7,  ;
                   'SWITCH', 8,  'MOUSE', 9,  'POCKET', 10, 'SCANNER', 11, 3 )
 

When there are so many items, better you keep the items in an array and use AScan.

Code: Select all  Expand view

local aItems := { 'COMPUTER','NOTEBOOK', 'PRINTERS', 'MONITOR', ;
                  'KEYBOARD', 'SWITCH', 'MOUSE', 'POCKET', 'SCANNER' }

< .... other code .. >

      :bBmpData := { ||  If(  oBrw:oTreeItem:oTree == nil, ;
             AScan( aItems, Trim(  oBrw:oTreeItem:cPrompt ) ) + 2,
             If( oBrw:oTreeItem:lOpened, 1, 2 ) ) }

 

Basically I suggested a code for setting bBmpData. How best to derive the bitmap number based on the data is to be decided by you.

[Silvio]

I MADE ALSO THIS TO SAVE ON A EXTERN DBF THE BITMAPS


USE TABLE ALIAS TABLE
TABLE->(DbSeek("G"))
DO WHILE TABLE->CveTab="H" .AND. !TABLE->(EoF())
AAdd(ahardBmp,TABLE->Bitmap)
TABLE->(DbSkip())
ENDDO
TABLE->(DbCloseArea())


....

WITH OBJECT oBrw:aCols[ 1 ]

AEval(ahardBmp, { |cBmpFile| oCol:AddBmpFile(cBmpFile)}


BUT THERE IS SOMETHING OF WRONG BECAUSE IT MAKE ERROR, I DON'T KNOW

[Silvio]

Nages,
I made

Code: Select all  Expand view

local aItems  :={}
 local ahardBmp:={}


USE TABLE ALIAS TABLE
   INDEX ON TABLE->CODE TO CODETABLE
   TABLE->(DbSeek("H"))
   DO WHILE TABLE->CveTab="H" .AND. !TABLE->(EoF())
        AAdd(aItems,TRIM(TABLE->DESCRI))
       AAdd(ahardBmp,TABLE->Bitmap)
       TABLE->(DbSkip())
    ENDDO
     TABLE->(DbCloseArea())



 USE HARDWARE
   INDEX ON Field->LABORATORY TO LABS
   SET ORDER TO "LABS"
   GO TOP
    DEFINE FONT oBold NAME "TAHOMA" SIZE 0,-12 BOLD
   DEFINE WINDOW oWnd TITLE "SAMPLE DBF shown as a tree with XBrowse width images"

   @ 2, 0 XBROWSE oBrw OF oWnd LINES CELL



     oBrw:SetTree( BuildTree(), {"TREE_LAB", "TREE_AULE", 'TREE_HARD' } )



 WITH OBJECT  oBrw:aCols[ 1 ]


AEval(ahardBmp, { |cBmpFile| :AddBmpFile(cBmpFile)} )

 :bBmpData := { ||  If(  oBrw:oTreeItem:oTree == nil, ;
             AScan( aItems, Trim(  oBrw:oTreeItem:cPrompt ) ) + 2, ;
             If( oBrw:oTreeItem:lOpened, 1, 2 ) ) }

END

ADD TO oBrw DATA oBrw:oTreeItem:Cargo[ 1 ] HEADER "MARCA"
   ADD TO oBrw DATA oBrw:oTreeItem:Cargo[ 2 ] HEADER "MODELLO"
   ADD TO oBrw DATA oBrw:oTreeItem:Cargo[ 3 ] HEADER "NUM INVENTARIO"


   ACTIVATE WINDOW oWnd

return nil
 

why not run ?

[stefano]

You can also change the bitmaps of the first tree ?

es
lab2 ... 1.bmp
lab3 ... 2.bmp
segreteria ... 3.bmp

Yes
Provide an array of resources in the second parameter of SetTree(...) method and then reassign oCol:bBmpData with your own codeblock to select the bitmap you want.
The default codeblock is

Code: Select all  Expand view

oCol:bBmpData   := { || If( ::oTreeItem:oTree == nil, aBmp[ 3 ], If( ::oTreeItem:lOpened, aBmp[ 1 ], aBmp[ 2 ] ) ) }

You can provide your own codeblock to show the bitmap you want conditionally.
