Hi all,

How do you change the text color of one tab or section of your status bar text?

Thanks.

A code snipped can be found in the purearea code-archive. but it seems not to be possible just to colorize one tab. only the complete statusbar.

and even this does not work under all OS Versions.

Simple, you can't natively. Only option is to specify one or more owner-draw field parts:

In the above code, how could you centre the text within an owner drawn status area ?

Thanks

Posted: **Sun Oct 04, 2009 2:05 pm**

Just add the #DT_CENTER flag to the DrawText_() command.

Hi!

I know, this is an old posting, but I need some help here:

I tried to make a procedure from the above code.
The original code works, after changing szText.l to szText.i in structure ODBSTEXT.
So this is not my problem I got.

When moving the needed code part into a procedure, there is no text "3" in field #2.

I modified the code a bit to show the problem.
Just run my code first with Test=#True. There is a red "3" in field #2.
Now change Test to #False in order to run the code in the procedure.
There is no text in field 2.

What did I miss? Here is the code:

Hello Lord,

The variable "Result" is unknown in your procedure.

Hi ccode!

ccode wrote:...

That's it!

Thank you for pointing this out.

Sorry for disturbing again.

I still have a problem with coloring the text in a statusbar field.

The above shown code works...

...until you try to resize the window by dragging the bottom right corner.

When doing so, there is an IMA at

Code: Select all

DrawText_(*lpdis\hDC, *osbt\szText, -1, *lpdis\rcItem, #DT_SINGLELINE | #DT_VCENTER | #DT_RIGHT)

in the window callback.
*osbt\szText gets an value of 11 there. No valid pointer to text anymore.

Somebody any ideas?

Hi!

The problem with field #3 is still there.

Even when replacing *osbt\szText with @"3 " in WindowCallback()

Code: Select all

DrawText_(*lpdis\hDC, @"3   ", -1, *lpdis\rcItem, #DT_SINGLELINE | #DT_VCENTER | #DT_RIGHT)

or defining a variable Text.s="3 " and replacing *osbt\szText with @Text

Code: Select all

Protected Text.s="3   "
DrawText_(*lpdis\hDC, @Text, -1, *lpdis\rcItem, #DT_SINGLELINE | #DT_VCENTER | #DT_RIGHT)

the field #3 in statusbar has still only a black rectangle when resizing the window.
But in this two variants the IMA is gone.

I know, Rashad has posted a canvas based solution:
viewtopic.php?f=12&t=71093
and I could use this, but I want to know, what went wrong here.

Hi Rashad!

Thank you for looking at this problem.

The good news is:
The first code you posted is working stand alone as it should.

The bad news are:
If incorporated in my existing code, the your first example
always gives me a red "BZ" without trailing spaces.
Inside WindowsCallback() the text @**osbt\szText has changed.

The second code shows a statusbar of almost doubled height
and with no text in any field.

Thank you for your help, but I'm giving up on this.
This is a issue for you experts, but not for me.

Posted: **Tue Jul 24, 2018 5:20 pm**

Thanks RASHAD works like a charm

That's interesting.
May I ask what Windows and what PB version you used to test?

I had in the just the chance to test the second version of Rashads code
on a Win81.1 with PB5.60(x64) while my sytem now is Win7, PB5.70(x64)beta.
On these the same result: not working.
