Hi All,

Seems like there may be a problem with updating the text on a frame.
I would like to have the time as the text of a frame but the code below does not update the frame.

Micromite Plus MMBasic Ver 4.7 Beta 37
Copyright 2011-2015 Geof
> option list
OPTION DISPLAY 48, 132
OPTION LCDPANEL ILI9341, LANDSCAPE, 21, 22, 23
OPTION TOUCH 18, 14
OPTION SDCARD 49
> list
Option explicit ON

Const pg9Frm = 1
Const pg9Val1 = 2

CLS
GUI FRAME pg9Frm, Time$ + " " + Date$, 0,13,MM.HRes,MM.VRes,RGB(Yellow)
GUI CAPTION pg9Val1, "???",10,70,LB,RGB(Yellow),RGB(Black)

SetTick 1000, PrnTime

Do

Loop

Sub PrnTime
Print DT$()

CtrlVal(pg9Frm) = DT$()
CtrlVal(pg9Val1) = DT$()
End Sub

Function DT$() As string
DT$ = Time$ + " " + Date$
End Function

Seeing this code does not cause an error it must be OK to do what I want.

Just had a though and added this line :-

Option Error Abort

BUT did not change problem.Edited by Bizzie 2016-01-21

I think a frame is a static element which wouldn't usually get changed during program execution.

I am not sure if overlapping GUI elements is wise, if fact I am sure that it is NOT wise, but this is one way of getting what you are after.

Option explicit ON

Const pg9Frm = 1
Const pg9Val1 = 2

CLS
GUI FRAME pg9Frm, " ", 0,13,MM.HRes,MM.VRes,RGB(Yellow)
GUI CAPTION pg9Val1, "???",20,20,LB,RGB(Yellow),RGB(Black)

SetTick 1000, PrnTime

Do

Loop

Sub PrnTime
Print DT$()

CtrlVal(pg9Frm) = DT$()
CtrlVal(pg9Val1) = DT$()
End Sub

Function DT$() As string
DT$ = Time$ + " " + Date$
End Function

All I did was create a blank space in the frame and positioned the caption to fill that space.

You could delete and recreate the frame each second but that is likely to upset any elements that are relying on the frame such as radio buttons.

Do you think that includes creating multiple GUI elements but keeping them hidden?

IE: Create all your GUI element after issuing GUI DEFAULT HIDDEN, but then just show the ones you want - see page 23 of advanced manual. In this way, all GUI elements are initially hidden, but technically speaking, they will all overlap - there is no way to avoid it, when you need several screens of GUI controls. However, you are only enabling the ones on that screen vis GUI SHOW.

Do you see any issues there?

...and I digress a little from the thread topic(apologies to OP), but watching any/all threads about GUI at the moment....

Smoke makes things work. When the smoke gets out, it stops!

I would like to put the time in the frame to save some space on the 2.4" screens.
If it was not allowed I would assume it would generate an error.

Hidden or disabled should be OK but having two GUI elements trying to detect the same touch is likely to cause grief.

I am not the best person to advise. I have done very little work with the GUI so far and what I have done has been very basic.

Overlapping FRAME and CAPTION seems to work OK but they are but passive elements. Adding input elements is where I would be careful.

I never thought of dynamically updating the caption in a frame which is why MMBasic does not check for that. But, it is easy to do. I am just finishing off the final version 5.1 so I will add that in before the close.

On overlapping GUI controls. Yes, you can have them overlapping so long as they are not looking for touch input. So, overlapping hidden controls is fine.

I have been playing around with a 7" SSD 1963 LCD a micromite 64 pin and RTC connected, using MMBasic 5.1 and trying to learn the GUI commands

Can someone explain WHY I'm getting the time in the GUI FRAME as well as displayed in the Frame where I actually wanted it?

Remember I'm still extremely new to programming and struggling to get things into my head.
Why does the code "have to have the CONST lines?

Also is it possible to specify a background colour for the frame?

Also is it possible to make the font inside the frame larger?

sorry for so many "weird" questions.

[code]
Option explicit ON
RTC GETTIME

Const abc = 1
Const bcd = 2
CONST cde = 3
CONST def = 4

CLS
GUI FRAME abc,"",50,50,600,350,RGB(RED)
GUI CAPTION bcd,"",325,220,LB,RGB(BLUE)

SetTick 1000, PrnTime
GUI FRAME cde,"" , 80,80,200,100,RGB(GREEN)
GUI CAPTION def, "Hello Lewis", 120,120,LB,RGB(WHITE)

Do

Loop

Sub PrnTime

CtrlVal(abc) = DT$()
CtrlVal(bcd) = DT$()
End Sub

Function DT$() As string
DT$ = Time$ + " " + Date$
End Function
[/code]
