I try to insert a explorerBar into a dialog with success but I want ask U some questions


First Question
I'd like to change the bitmaps of button colllapse of each panel with mine,
how I can make if the button for open is open.bmp and for close is close.bmp
as this picture

and if not want show any button (as this picture) how I can make ?


Second question
On each panel I must use addlink to insert a item
I want use a big bitmap for each item, can I create a space from a item to another ? or create a link to n position ?
Can I set the font for each item ( link) ? and How ?





Third question
I'd like to create on each panel a black border because is professional and elegant border as this picture



Another question
can insert a watermark image trasparent on each panel ?

Domenico,

1) Class TExplorerBar manages Class TTaskPanel objects. These objects call to functions BmpEBExpanded() and BmpEBCollapsed() that return the bitmaps to paint for both states.

Simply implement your own functions BmpEBExpanded() and BmpEBCollapsed() in your own PRG and you will be overiding the ones provided by FWH.

You can read the bitmaps from files (BMP) in the disk, or load them from your resources, i.e.:

Code: Select all  Expand view

function BmpEBExpanded()

return ReadBitmap( 0, "expanded.bmp" ) // reading it from an external BMP file
 

or

Code: Select all  Expand view

function BmpEBExpanded()

return LoadBitmap( GetResources(), "expanded" ) // load it from your resources, where "expanded" is the identifier of your bitmap
 

With these questions and surely more to come, we will be completing the wiki docs about Class TExplorerBar:
http://wiki.fivetechsoft.com/doku.php?id=fivewin_class_texplorerbar
Class TTaskPanel docs:
http://wiki.fivetechsoft.com/doku.php?id=fivewin_class_ttaskpanel

and if not want show any button (as this picture) how I can make ?

Simply make those functions return a zero:

Code: Select all  Expand view

function BmpEBExpanded()

return 0
 

or

Code: Select all  Expand view

function BmpEBExpanded()

return 0
 

Second question
On each panel I must use addlink to insert a item

Can I set the font for each item ( link) ? and How ?

By default the Class TTaskPanel expects to manage a 16x16 pixels bitmap for each item. If you want to use a different size then the logic of the Class TTaskPanel should be modified.

TTaskPanel objects are true Windows controls, so in fact you can place any control on top of them, simply using the typicall FWH sintax: @ ..., ... OF oPanel

By default TTaskPanel items are FWH Class TUrlLink objects, so you can modify all the properties that are available to those objects: http://wiki.fivetechsoft.com/doku.php?id=fivewin_class_turllink

Third question

You can easily modify Class TTaskPanel Method Paint() to enhance it the way you may want it.

Just keep in mind that Class TTaskPanel obejcts use a Windows "region" to obtain the curved effect on its top corners. So you can use FWH functions to paint boxes to implement such border, but the corners will require a special coding surely using function Ellipse() calls.

When you review the source code and the docs of the Class TExplorerBar and its related classes, you will realize the amount of complexity that automatically manages. This is the first version of this Class, and you may expect enhancements for it in next versions based on users requirements. By now we do believe that if offers an very good level of functionality.

Another question
can insert a watermark image trasparent on each panel ?

As Class TTaskPanel objects are true Windows controls, you can easily modify the Method Paint() to display a background image, etc. Full source code is available so feel free to modify it for your own needs

thanks antonio,
I made one add for now on your class Explorer
I insert a border ( to simulate a shadow on each panel or insert a border with another color)
it run ok only there is an error on round right angle

but when I use a panel with lspecial = .t. it not show the error as you can see on this picture



any Idea ?

RESOLVED !!!

and i add also the method WaterImage() as you ca see on this picture



only I can use alpha bitmap because I not found the solution with normal bitmap because it show the bitmap on white color

Domenico,

Very good

If you share your changes with all of us, then we will incude them for next FWH 10.7 version

It ok for me only I have a problem with normal bitmaps because when I use them the taskpanel show it bad ( on reverse white)
Only it show good the bitmap only Alpha Bitmap tyoe.
as you can seee on this picture


then I made also a small include to create panel object

for sample

ADD PANEL oPanel1 of oExBar PROMPT "One" ;
BITMAP "..\bitmaps\32x32\people.bmp" ;
BORDER BORDERCOLOR CLR_BLACK ;
WATERIMAGE "user.bmp" ;
COLORS CLR_RED,CLR_YELLOW

ANTONIO,

I made a test with

if SetAlpha()
ABPaint( ::hDC, nLeft, nTop, ::hWaterImage, nAlphaLevel )
else
DrawTransparent( ::hDC,::hWaterImage, nTop, nLeft )
endif


When the bitmap is NO ALPHA BITMAP it show the bitmap in white as you can see on picture





H0w I can make to show the image on trasparency as the image you can see on window xp explorer as this picture ?

Antonio,
Now I saw the Daniel Function FwWater but It not run ok here :

METHOD WaterImage() CLASS TTaskPanel //add by MdaSolutions
if !Empty(::cWaterImage ) .and. !::lCollapsed

::hWaterImage := ::LoadImage( ::cWaterImage )


if ::hWaterImage != 0
nWidth = nBmpWidth( ::hWaterImage )
nHeight = nBmpHeight( ::hWaterImage )
nTop := ::nHeight - nHeight-1
nLeft := ::nWidth - nWidth-10
nBottom := nTop + nHeight
nRight := nLeft + nWidth
nAlphaLevel := 20
FWWaterMark (::hWaterImage)

if SetAlpha()
ABPaint( ::hDC, nLeft, nTop, ::hWaterImage, nAlphaLevel )
else
DrawBitmap( ::hDC, ::hWaterImage, nLeft, nTop )
endif
DeleteObject( ::hWaterImage )
ENDIF
ENDIF
return nil

Mda...


FWWaterMark return a Bitmap handle

Code: Select all  Expand view

METHOD WaterImage() CLASS TTaskPanel //add by MdaSolutions
   local hBmp

   if !Empty(::cWaterImage ) .and. !::lCollapsed
   
      hBmp := ::LoadImage( ::cWaterImage )
     
      if ::hWaterImage != 0
         nWidth = nBmpWidth( hBmp )
         nHeight = nBmpHeight( hBmp )
         nTop := ::nHeight - nHeight-1
         nLeft := ::nWidth - nWidth-10
         nBottom := nTop + nHeight
         nRight := nLeft + nWidth
         nAlphaLevel := 20
         ::hWaterImage = FWWaterMark( hBmp )
   
         if SetAlpha()
            ABPaint( ::hDC, nLeft, nTop, ::hWaterImage, nAlphaLevel )
         else
            DrawBitmap( ::hDC, ::hWaterImage, nLeft, nTop )
         endif
         DeleteObject( hBmp )
      ENDIF
   ENDIF
return nil
 

thanks Daniel now run but I see also the bitmaps square not transparent !!!
look it please



and i tried also with a Alphabitmap ( fwh\bitmaps\AlphaBmp\trash.bmp) same error
