Hello,

for the Vtools, i startet with the Bar-test.
There are some problems :

1. I want to change the Bar-Color from inside a Dialog with a button.
oBar:bClrGrad ( Window-Bar oBar ) has to be red now.
But the button doesn't change the color.





2. I wanted a buttonbar in the dialog
it was no problem before.
Now i get a error :



There is a error :

Now i get a error :

Try defining your buttonbar in the ON INIT clause.

Thank you very much
One problem solved.





A color-change-test inside the dialog :

REDEFINE BUTTONBMP oBtn1 ID 10 OF oDlg ;

Maybe still a solution for the runtime-problem.
I want, that the user can test different styles and colours
for the bars in VTOOLS.

oBar1 is NIL. I strongly suggest to use -w2 compiler switch.

Hello Enrico,

I changed from Red to Blue.
The result is shown in a extra dialog ( not runtime )



What do you think about this solution ?

Best Regards
Uwe

Uwe,

Please declare local oBar1 in FUNCTION NEW_DLGBAR()

Antonio,

thank You very much.

In all tests ( xbrowse, bars .... ) maybe it is better, to keep the old setting
and show changes in a extra dialog ?
The user can see the difference of the original and the changes.

As a sample : the original dialog shows the bar only RIGHT with Red color.
The test shows TOP and RIGHT in Blue.

Best Regards
Uwe

I am responding to this limited issue raised by Mr Uwe

>>
1. I want to change the Bar-Color from inside a Dialog with a button.
oBar:bClrGrad ( Window-Bar oBar ) has to be red now.
But the button doesn't change the color.
>>

At present, the code of bar.prg and btnbmp.prg does not allow change of gradient at runtime.
The following changes are needed to change the gradient color at runtime.


First in the application code :
the code:

be changed as:


In the BtnBmp.Prg:

orginal code at Line 724

be changed as :

In the Bar.Prg:

After line no: 751, before ::DispEnd( aInfo ), the following code is to be inserted:

After doing the above changes, it is possible to change the gradient color at runtime.

Hope Mr. Antonio agrees with the above changes.

Thank you very much.

I'm busy with testing.
I think, i finish the bar-modul at first,
then carry on with the rest.

Soon the first tests have good results.
It works fine with the color-selections.
There has to be a field for the source-result
like :

oBar:bClrGrad = { | | { { 0.50,16054371, 8388608 }, ;
{ 0.50, 8388608,16054371 } } }

This must be stored in a project-file.



When i close a Test-diolog, I will store the color-result
to the Dialog-bar ( Red )
After a new test it is possible to see the difference to the test,
done before.

Best Regards
Uwe

Hello,
to change a buttonbar in a clean way at runtime, seems
to be nearly impossible.
The old buttons are visible again with mouse-connection.
the old bar created before, is still active.
I have to find a different solution.

I wanted to use the solution from nageswaragunupudi.

nageswaragunupudi

i added the lines to Bar.prg
When i start my exe-file there is a error.

---

In the Bar.Prg:

After line no: 751, before ::DispEnd( aInfo ), the following
code is to be inserted:
Code:

for n = 1 to Len( ::aControls )
::aControls[ n ]:Refresh()
next
::DispEnd( aInfo )

---

When i start the application, an error occurs :

Stack Calls

Called from: .\bar.PRG => GRADIENTFILL(892)

maybe the lines are inserted on a wrong position ?

Best Regards
Uwe

>>>

>>>
This means NIL is being passed on the GradientFill function instead of a valid Gradient Array.

Please check if you made all the corrections I posted earlier 'exactly' . I confirm it works for me here.

Hello,

If found the ERROR

The reason is not the code change.

The error occurs, when i include bar.prg in the link file.
There is no syntax-error in the compile-run, only when i start the exe.

When bar.prg is used from Lib and not included in the link file, it works.
It seems, i cannot add the lines to the prg.

File stamp : BAR.prg / 29.418 / 30.07.2008

PRG = \
bar.PRG \ <====
btnbmp.PRG \
bartest.PRG

Maybe the file bar.prg is different to the library ?

As a test, i started a project with the FWH-sample TESTGRAD.prg

The same happend. When i start the EXE, i get the error.

I use a normal make-file :

#Borland make sample, (c) FiveTech Software 2005

HBDIR=d:\xharbour
BCDIR=d:\bcc55
FWDIR=d:\fwh

.path.OBJ = .\obj
.path.PRG = .\
.path.CH = $(FWDIR)\include;$(HBDIR)\include
.path.C = .\
.path.rc = .\

PRG = \
bar.PRG \
btnbmp.PRG \
testgrad.PRG <=== FWH-sample

PROJECT : testgrad.exe

testgrad.exe : $(PRG:.PRG=.OBJ) $(C:.C=.OBJ) testgrad.res
echo off
echo $(BCDIR)\bin\c0w32.obj + > b32.bc

# OBJ-Liste

echo obj\bar.obj \
obj\btnbmp.obj \

echo testgrad.exe, + >> b32.bc
echo testgrad.map, + >> b32.bc

# Fivewin Lib`s für xHARBOUR

After a new design, the old bar is still visible in the dialog.
The new one is shown on top of the old one.
