Hi, Diego,

Do you happen to have solution for xbpcolumn heading with text & ico? I
wanted to add to the column heading with a triangle ico after the text to
show the column has the active order.

I have found many of your example in xbpbrowse even with ownerdraw on text
(highlight.prg) but just couldn't figure how to add ico.

Please enlight me

TIA

Paul

Hi,

Two different ways to solve it (You will need to adjust it).

Hi Diego,

As always, awesome solution. 

However, I have forgot to mention i need to draw the ico/marker after the
xbpcolumn has been created. Meaning when the heading is click the
ico/marker is draw on that heading and the ico/marker on the previous
xbpcolumn heading will be remove.

How do i do that?

TIA

Paul

Hi Diego,

Another brilliant solution. Didnt expect it can be coded this way. But it
laed me to understand more about ownerdraw.

Many thanks again

Hi Diego,

Just my curiosity, i believe this line remove the previous heading's marker 
by redrawing the heading.

_oCol:heading:invalidateRect()

However, which method does it invoke? Because the INLINE METHOD 
CustomDrawCell() will definately redraw with marker. 

TIA

No, just repaint the "old" heading

_oCol:= ::oColOrder
::oColOrder:= oCol                           This previous line eliminates 
it.
_oCol:heading:invalidateRect()

Very interesting.
I've been reading along as your samples are always worthwhile looking into.
Drawing an arrow with just a few horizontal lines. I would never have
thought that would give such a nice result.

Thanks a lot.

Yup. I cannot agree with you more. I was originally looking at ico till he
show the example.

Hi Diego,

Now i understand how it works. The "old" heading just get repaint with the
field name as caption created earlier.  The "new: heading will get an
additional marker paint on it.

The example is getting better & better but i always cant get it to compile
unless i add this line to link xbpbrowse

#pragma Library( "XppUi2.lib" )

Other than that your sample works like a champ even you didnt test it. =

Thank you again

Paul

Paul,

Although here compiles without problems (w10 & Xbase++ 2.00.951), I added 
the pragma directive to the sample.

Hi Diego,

Ok. Tq. We use xbase++ 1.90.355. Maybe thats the different.

Just 1 more question. I use :Enter & :Leave to change the mouse pointer
shape in the heading.

#define XBPSTATIC_SYSICON_UPARROW   10
#define XBPSTATIC_SYSICON_NOT       11
#define XBPSTATIC_SYSICON_APPSTART  12
#define XBPSTATIC_SYSICON_HELP      13
#define XBPSTATIC_SYSICON_PEN       14
#define XBPSTATIC_SYSICON_HAND      15

FUNCTION SetSysPointer( oXbp, nId )

  IF nId <= XBPSTATIC_SYSICON_SIZENS
     RETURN oXbp:Setpointer( , nId, XBPWINDOW_POINTERTYPE_SYSPOINTER )
  ENDIF

  IF nId <= 10
     nId := 103 + (nId - XBPSTATIC_SYSICON_SIZENS)
  ELSE
     nId := 108 + (nId - XBPSTATIC_SYSICON_SIZENS)
  ENDIF

RETURN oXbp:SetPointer("USER32.DLL", nId, XBPWINDOW_POINTERTYPE_POINTER)

oHead:Enter := {| aPos, uNIL, o | SetSysPointer(o,XBPSTATIC_SYSICON_HAND)}

oHead:Leave := {| uNIL1, uNIL2, o |
SetSysPointer(o,XBPSTATIC_SYSICON_DEFAULT)}

However, sometimes the pointer never change shape when enter from
left/right heading if the size pointer popup. I've check at Alaska website
it seems to be related Pdr 4590 & has not been solved.

Have you encounter this before & any workaround? Maybe the column size can
be fixed so that the size pointer will not show. But how to fix the column
size?

TIA

Paul

I would not change the mouse pointer, but if you want to change it...

You have to keep in mind that the development of Alaska's guys is special, 
sensitive to a small region of the region of the heading, and the assignment 
of a new pointer comes into collision with that development. Therefore, if 
you want to develop what you want, you have two options:

1. Modify the original Xbase++ code (surely easy if you have it).
2. Use the power of OOP and modify the standard behavior of the XbpColumn 
class. In this way, the code will be compatible with future possible changes 
of XbpColumn class. That's what I've done in the new sample (You will have 
to customize a more appropriate pointer).

Regards. Diego

Hi Diego,

Once again, you made my day. I will use the 2nd approach, not only to stay
compatible, but to explore more power with OOP.

I like to buy you lunch for the time taken to make the sample. Please email
me your paypal ac.

Paul

Hi Diego,

i have encountered a problem trying to use the sample. All the text in the
brow data & heading have disappeared. This is 1st step, to subclass &
prepare ownerdraw. If i remove the line ::drawMode:=XBP_DRAW_OWNER at CLASS
tdcCol (2nd last line), brow text is ok.

I have attached the source from both your sample & my code (tdHibrow) for
comparison. For ease of reading, unrelated code is removed & pls ignore the
params.

From the doc -> 'The drawing mode must be assigned to :drawMode before the
method :create() is executed.'. I suppose i have done it right. Is there
something else i have missed?

TIA 

Paul

where is your CustomDrawCell() ???

Hi,

Please refer to the sample attacjment from Diego.

However, i have found the problem. Please refer to the following post.

Thank you

Hi all,

I have found the where the problem is. There is a method in the tdcBrow
where it process event for mouse wheel.

* For custom mouse wheel handling
METHOD NewBrow:HandleEvent(nEvent,Mp1,Mp2)

IF nEvent == xbeM_Wheel .AND. ::lWheelCtrl
   IF Mp2[2] > 0
      ::up()
   ELSE
      ::down()
   ENDIF
   ::refreshall()
   ::skipEval()
ELSE
   ::xbpBrowse:HandleEvent(nEvent,Mp1,Mp2)
ENDIF
RETURN self
*

Its used to skip record by mouse wheel. If this method is remarked, all
captions return to brow. Otherwise captions disappear.

Guess what is the cause of the problem?

TIA 

Paul

Hi,

I dont think thats the issue cause i can compile his sample with 1.90.355 &
get expected result. Only when i try to add it to my app than the problem
arise. Maybe something to do with my internal code or Topdown code. Still
checking.....
