[perl-win32-gui-users] richedit setting background-color of some text

[Richard Bennett]

(sorry if this message comes through twice)

Hi,

I am parsing a textfile into a richedit control, and want to highlight
certain words.
I can do this by changing the fontcolor like this:

if(/wordtohighlight/) {
$Textbox->SetCharFormat(-color => "#55");
}
while parsing the file,

but I can't find how to change the background color for the same words (not
the whole page)
I know the control supports it, as it displays text that was highlighted in
Word just fine.
Any ideas?

Richard.

Thanks for the reply, it might. However, it is not clear what I do in the 
timer event. Should it just be a NOOP so that the event simply interrupts 
processing (do I even need it)? If a button click has occurred will the 
click event will be triggered or do I need to check something in the timer 
event to see if the button was clicked?

[perl-win32-gui-users] AddTimer problem

It seems that even the simplest things get complicated.

I created a timer thus:

my $timer1=$window->AddTimer('T1',250);

How much simpler can one get then that? Anyway, this produces an error at 
every timeout:

"Use of uninitialized value in subroutine entry at myscript.pl line 183.:

Line 183 is:

Win32::GUI::Dialog();

I know the timer is causing the problem because if I comment it out the 
error goes away. What value is it talking about? How do I find out? What 
can I do to fix this? TIA.

Thanks for the suggestion. It was worth a look but alas did not help.

RE: [perl-win32-gui-users] Click subroutine doesn't get control when script is executing

[Stuart Arnold]

In the typiucal windows way (which we can do in PERL), is to start a
TIMER.
The classic to this approach is a "setup" pogram with the prograss bar.

When you start your script, you will need to set a WM_TIMER for some
time slice,
eg, every 2 seconds.

If you're building your own GUI, then before the
WitEvent/DoModal/Whatever, you;ll want
to put it in there.


Here's the Win32::GUI package's description...Hope this helps out :)

Timer
The Timer object is a special kind of control: it has no appearance, its
only purpose is to trigger an event every specified amount of time. 

The synopsis to create a Timer object is: 


new Win32::GUI::Timer( PARENT, NAME, ELAPSE )



PARENT->AddTimer( NAME, ELAPSE )


NAME
the name for the Timer object (used to lookup the associated event). 

ELAPSE
the number of milliseconds after which the Timer() event will be
triggered. 

Once you've created the Timer object, you can change the ELAPSE
parameter with the Interval() method, or disables it with the Kill()
method. Note that Kill(), despite of its name, does not destroy the
Timer object, so you can re-enable it later with Interval(). 

Example: 


# creates a Timer that is called every 1 second

$Window->AddTimer( "Clock", 1000 );



sub Clock_Timer {
print "one second passed.\n";
}


Methods: Interval, Kill

I have a script that is started by a button. It can be a long process
and I 
would like to give the user the option of cancelling execution at any
time. 
Unfortunately, it seems that when the script is running all buttons
become 
disabled or at least the click events are never allowed to get control.

How do I set up a cancel button and click event that can interrupt
script 
processing? TIA.
