Developers: Need Help on v2.5.0 to Change Fade Tool Bar to Hide

[manuprenlair]

Hello Jesper,

This is working!

Just one thing, when the toolbar appear after mooving the mousse, actually it not desapear again after a delay, because the Fade timer is not re-triggering

 m_fade_timer.Start(5000)

and also it need to set

m_opacity = 255;

.

The class ocpnFloatingToolbarDialog from m_fade_timer.Start() come is not know in chcanv.cpp.

What is the right method to do this job?

(I am sorry, I know C but just a little C++ and my lake made me the job difficult without your help, because I don't master class concept..:-/ )

Thx

Emmanuel

I suggest you put that code into the MyFrame::SurfaceToolbar() method in chart1.cpp, otherwise you will need a lot of modifications to be able to reach the toolbar object from chcanv.cpp.

Hello Jesper.

Like version 3.0.0 is release, I decide to port the "hide toolbar" on it.
So what I did:

I modify the chcanv.cpp like you told me (line 7698):

        }
//EFI: This is for Hide-ToolBar modification
        gFrame->SurfaceToolbar();
#endif



        //  Send the current cursor lat/lon to all PlugIns requesting it
        if(g_pi_manager)

then I modify chart1.cpp:

void ocpnFloatingToolbarDialog::FadeTimerEvent(wxTimerEvent& event)
{
      if(g_bTransparentToolbar && !g_bopengl)
      {
            DoFade(128);
//EFI: This is for Hide-ToolBar modification
                Submerge();
      }

      m_fade_timer.Start(5000);           // retrigger the continuous timer
}

So I made only basic modification you gave.
What's happend:

I start OpenCPN and dont touch the mouse:
The tool bar appear
then 5s latter the tool bar desappear ( it's what we want)

Then I move the mouse:
The tool bar appear, but icon are no draw.
Then 1s latter the tool bar disappear.

I move the mouse but the tool bar never appear again ..

So ... what's append

Hope you could help me

You haven't removed the code that tries to make the toolbar transparent, maybe that's why it's not drawing properly. (If your system doesn't support transparency).

When you get that working, I would also suggest that you only call SurfaceToolbar() if the toolbar is actually hidden. As you have it now, the toolbar is redrawn on every mouse move, which is inefficient and unnecessary.

Héhé Jesper

The problem came from the fact I call SurfaceToolbar at each mouse event!
You'are right!
I think about that this mornig and I just test it at work
It's work now!
And I just read your post with the same idea.

The transparency was not the problem 'cause I test modification on a system where it's work.

Well, now I need to put all modification I made on 2.5.0 code on 3.0.0.

Thanks Jesper for your help
