xbrwdisk change directory

Dear Mr. Rao,
I try to extend xbrwdisk.prg to change directory with a click on a button.
I use :SetTree.
But then inside xBrowse it adds a new column item.
Can you please help me.

Best regards,
Otto

Code: Select all

      @ 0,0 ;
      BUTTON "Change directory" ;
      ACTION ( aDrives := { "c:\fwh\samples"}, oTree := MakeTree( aDrives ),  ;
            oBrw:oTree := oTree, oBrw:GoTop(),oBrw:Refresh() );
          OF oDlg
 
and also change :bBmpData as below:

Code: Select all

      :bBmpData   := { || If( Right( oBrw:oTreeItem:cPrompt, 1 ) == ":", 4, ;
                          If( 'D' $ oBrw:oTreeItem:Cargo[ 5 ], ;
                          If( oBrw:oTreeItem:lOpened, 1, 2 ), 3 ) ) }

Dear Mr. Rao,
Many Thanks. I made the changes, and everything worked.

Is there any way that you can seek in the tree?

Best regards,
Otto

Dear Mr. Rao,
I tried to have the tree open at the directory change to use ToggleFolder.
This works. But is this the way how to do it.

Code: Select all


@ 0,0 ;
      BUTTON "Change directory" ;
      ACTION ( aDrives := { "c:\fwh\samples"}, oTree := MakeTree( aDrives ),  ;
            oBrw:oTree := oTree, oBrw:GoTop(),oBrw:Refresh(), ToggleFolder( 25,25,1,oBrw:aCols[ 1 ],oBrw:aCols[ 1 ]:bLDClickData ) );
          OF oDlg
Best regards,
Otto

Instead, change MakeTree() like this

Code: Select all

static function MakeTree()

   local oTree, oItem, n


   TREE oTree

   for n := 1 to Len( aDrives )

      TREEITEM oItem PROMPT aDrives[ n ]
      oItem:Cargo    := { aDrives[ n ], 0, CtoD( '' ), Space( 8 ), 'D', ;
                        aDrives[ n ] }

      if Len( aDrives ) == 1
         oItem:SetTree( SubTree( oItem ) )
         oItem:Open()
      else
         oItem:bAction  := { |o| o:SetTree( SubTree( o ) ), o:bACtion := nil }
      endif

   next

   ENDTREE

return oTree
 
This is a very old program.
I am considering revising it.

Dear Mr. Rao,
Thank you for your help.
Now Harbourino Manager is ready.
Do you think you will provide "Search" for treeview shortly?
Have a lovely weekend and best regards,
Otto

Dear Mr. Rao,
Thank you. In the meantime I use a workaround and have finished Harbourino Manager.

This video shows the Harbourino Manager. All functions can be carried out from one console.

https://mybergland.com/fwforum/harbourinomanager.mp4

If anyone would like to install and try Harbourino, please just write me. Then I can give you a download link.

Best regards,
Otto
