OpenCPN on a 8" Touchscreen

Hi,

I downloaded the recent stable release (3.0xx) for Ubuntu 10.04 LTS and I am running it on a 8" Xenarc Touchscreen on my boat as my main chart plotter. I was out sailing at night the other day as a shakedown for this setup and I quickly figured out that the buttons are a bit too small. They work but I ended up touching the MOB button more than once. :-(

Is there anything I can do to alter the size of the buttons, and prevent them from going transparent. (I do software development, so if I need to get into the source code, I would be willing to do that.)

Also, I have no right click option with the touchscreen driver for 10.04, so I may try Ubuntu 12.04 since the screen is better supported in that version (I have been told).

Of course Ubuntu 10.04 was not designed for touch screen operation so the OS buttons are also too small. Any suggestions for a different Linux distribution that is better geared for touch screens?

Thanks, Dave

Go for it!!

You'll need the current beta version (has a few minor bugs but can be used for development). Size of buttons can be modified without altering the source code, refer to User Interface Styling | Official OpenCPN Homepage

I would recommend 12.04 also because 10.04 comes with an out-of-date version of wxWidgets.

Transparent toolbar is just a settings checkbox.

So I can just tweak the XML file to change the buttons? That is simple.

I'll load up Ubuntu 12.04 on a different PC and try this out. If it works, I will just swap hard drives. I left the PC running 10.04 on the boat, since it does work, just not as well as I would like. :-)

Thanks! Dave

Well you will need to redraw the bitmaps too, but it's still pretty simple!
