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.

Hi,

Playing with GUI stuff for the first time on a 7" display on an F4.
I have this code for a display box & text using CTRLVAL.
However, I cannot get the Font size to change. Stays at No 2 (Small).

FONT seems to work on a Caption box OK.

What am I doing wrong?

gui displaybox #1, 10, 415, 330, 50, grn, cBGnd
font 5,1: CTRLVAL(1) = "BACKLIGHT = " + str$(B_Light)

Also, how do you use DAY$? I can't get any sense out of it with: PRINT DAY$

Thanks

Brian

DAY$(date$) Returns the day of the week for a given date as a string �Monday�, �Tuesday� etc. The format for date$ is �dd-mm-yyyy�. Use NOW to get the day for the current date, e.g. ? DAY$(NOW)

Don't know much about the GUI commands but I suspect the font size is associated with the control so needs to be set before the GUI command

Thanks Peter.

The DAY$ fn makes sense now.

I'll try putting the Font cmd before the GUI cmd & see what happens.
I don't know much about them either.

Brian.

OK

This works with the FONT command before the GUI Displaybox command. (The FONT statement after the GUI Displaybox command didn't).

FONT 4
gui displaybox #1, 10, 415, 330, 50, grn, cBGnd
CTRLVAL(1) = "BACKLIGHT = " + str$(B_Light) + "%"

The other examples I was following had the FONT statement immediately before the text as I originally posted.

Got DAY$ tested OK thanks Peter
