how to change the size of the Toolbar Button?

[manuprenlair]

Hello all!

My project to make an Open Hardware plateforme to run OpenCPN is in a good way. I will talk about soon.

But for now I am under test with a tactil screen of 7".
And I want to be able to have bigger button on the tools bar. (to use it with my finger)

Is it possible without modify the code ?


Could I have some help to do that (even if I need to re-compile the code)?

Best Regards

Manu...
It's not possible to do it without touching the code a little bit. Good news is that it's very simple.
Lets say you want the icons 50% larger (48x48 pixels instead of the default 32x32) and don't mind that the enlarged icons will not be as smooth:
In chart1.cpp (line 1586 in the current 2.6 beta code from git):
Change

m_ptoolbar->SetToolBitmapSize(wxSize(32,32));

to

m_ptoolbar->SetToolBitmapSize(wxSize(48,48));

in bitmaps/icons.cpp (in function initialize_images()):
Change all lines like

_img_WHATEVER= new wxBitmap(wxImage(sm));

to

_img_WHATEVER = new wxBitmap(wxImage(sm).Scale(48,48));

If you want a different size for the icons, just use other number instead of 48...

Then rebuild opencpn.

Or you can regenerate the icons from the SVG sources to be the size you need and look pretty - If you are on Linux and have Inkscape and perl, read the create_all.sh script in src/bitmaps

Hope it's clear
