Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Good evening all..!

I was trying to create button touch areas on top of small BMP file images to make graphic looking buttons but I can't seem to get past the command...

touch size 100,100
touch create 0,100,100

do while touched(0)=0: loop

the create produces a syntax error... not sure why...

PDF says:

TOUCH CREATE r, x, y
Will create a touch sensitive area on the screen with no
corresponding visible image. 'r' is the reference number. 'x' and 'y'
are its position in pixels

Has anyone else tried this..?

What line creates the syntax error?

Hi Geoff..!

It's the create line "touch create 0,100,100" that trips the syntax error...

Not sure why.. I think I am typing it in right..

Damn, it is a bug.

The workaround is to add two dummy parameters to the command.

For example:

TOUCH CREATE 1, 100, 100

will cause a syntax error, while

TOUCH CREATE 1, 100, 100, "", 0

will work correctly (the last two parameters are ignored).

I will fix it in the next release.

Good evening fine Sir.

Thanks for the quick response.. Using the workaround is no problem..! Just glad there is a way to continue testing...

Update: Looks like the workaround makes it function correctly... (sweet!)

Still working on adding objects to the UI Lib...

Thanks much Geoff.!!Edited by Zonker 2013-11-20
