wxTimer and the new dynamic event system... Topic is solved

[ouch67]

So I'm trying to get these 2 to work together.

I can't seem to find one example of using a wxtimer with the new bind event commands.

The wxTimerEvent also doesn't seem to have an event type assigned to it which is also throwing me off...

any help would be appreciated.

[catalin]

The event type is wxEVT_TIMER. The rest should be just like using Bind in any other situation (connect the timer's target to that event type).

[ouch67]

ok, I think I got it now except the bind command isn't working.

It's telling me it's out of scope. I'm calling it in OnInit, should I not use it there? Where do you set bindings up at?

my code so far is this:

Code: Select all

    wxTimer* m_timer;
    m_timer = new wxTimer();
    m_timer->SetOwner(this);

    Bind(wxEVT_TIMER, &slashanim, this);
    m_timer->Start(3000);

[catalin]

What exactly is out of scope?
Binding there is ok.
Is m_timer supposed to be a member variable? If yes then you probably don't want to do
wxTimer* m_timer;

[ouch67]

it specifically says the bind command itself is... which is a bit scary... heh...

I'm using the SVN branch of 2.9

The log says:

Code: Select all

|359|error: 'Bind' was not declared in this scope|

I've also tried to declare:

#include <wx/event.h>

I still get the same problem

[doublemax]

Which platform/compiler? Bind is not available everywhere.

Code: Select all

/*
   If this is defined, wxEvtHandler::Bind<>() is available (not all compilers
   have the required template support for this and in particular under Windows
   where only g++ and MSVC >= 7 currently support it.
 */
#if wxCHECK_GCC_VERSION(3, 2) || wxCHECK_VISUALC_VERSION(7)
    #define wxHAS_EVENT_BIND
#endif

[ouch67]

I'm using TDM mingw 4.5.2 (32bit) on windows 7 64bit.

[doublemax]

Can you check if the above check evaluates as true that wxHAS_EVENT_BIND gets defined?

[ouch67]

It's not defined, I wonder why?

also I did a search for:

#define wxHAS_EVENT_BIND
and it didn't come up with anything in the 2.9 trunk, where did you find that code snippet?

[doublemax]

It's in include/wx/features.h

I hope you didn't get the SVN branch from wxWidgets/branches/WX_2_9_0_BRANCH
You want wxWidgets/trunk

Just making sure...

[ouch67]

and yes I have that branch of 2.9.

yeah that code is not there:

when I compile and use the svn trunk version i get a no matching function call for Bind.

and it says I do have wxHAS_EVENT_BIND defined...

[doublemax]

"no matching function call" is a different error. I guess just the parameter list is wrong.

http://docs.wxwidgets.org/trunk/classwx ... e03db66e5c

[ouch67]

I actually just had a typo in my function declaration... but it works great, thanks again.

But why doesn't WX_2_9_0_BRANCH have these dynamic events? it's a function introduced in 2.9 right?
