Android Question Designer / Variable

[FrankDev]

hello

Question about the designer.

is it somehow possible to use variables ?
I need to know a calculated value again and again.

Greetings
Frank

 

[DonManfred]

AFAIK no.

 

[William Lancee]

More information needed.
What property do want to modify?
What do want to make a variable?

 

[klaus]

Yes you can.
Example:
Calculate the width of three Buttons covering the full screen width with a given space.

Space = 10dip
Width = (100%x - 4 * Space) / 3
Button1.Left = Space
Button1.Width = Width
Button2.Left = Button1.Right + Space
Button2.Width = Width
Button3.Left = Button2.Right + Space
Button3.Width = Width

Hello Klaus,

this is exactly what I was looking for.
My problem was, I had tried to dim the variable.

that did not work. On the idea not to dimension the variable I did not come

Thanks !!!!!

Best regards
Frank

Button3.Width = Width

I also did not knew it. Thanks.

Hello @klaus ,

I had used 'breite'.

That did not work.

Without apostrophes, I hope.

with ' does not go ????

 

[klaus]

I had used 'breite'.

What does not work?

The code below works!

Spalte = 10dip
Breite = (100%x - 4 * Spalte) / 3
Button1.Left = Spalte
Button1.Width = Breite
Button2.Left = Button1.Right + Spalte
Button2.Width = Breite
Button3.Left = Button2.Right + Spalte
Button3.Width = Breite

@klaus

Breite = (((panNumbers.Width - 22dip) - (panNumber1.width * 5)) / 4) + panNumber1.width

->>Die Datei ObfuscatorMap.txt wurde im Objects-Verzeichnis angelegt.
Kompiliere Layoutcode. Error
Unassigned variable: 'width'


Width = (((panNumbers.Width - 22dip) - (panNumber1.width * 5)) / 4) + panNumber1.width

works

 

[klaus]

You need to show the entire code in the Designer.
It seems that you have still somewhere a variable width.

 

[FrankDev]

only this code
I had also tried other variable names - without sucess

'All variants script
AutoScaleAll

Trenner1.Width = 2dip

width = (((panNumbers.Width - 22dip) - (panNumber1.width * 5)) / 4) + panNumber1.width

panNumber2.Left = panNumber1.Left + Width
panNumber3.Left = panNumber2.Left + Width
panNumber4.Left = panNumber3.Left + Width
panNumber5.Left = panNumber4.Left + Width

panNumber7.Left = panNumber6.Left + Width
panNumber8.Left = panNumber7.Left + Width
panNumber9.Left = panNumber8.Left + Width
panNumber0.Left = panNumber9.Left + Width

 

[klaus]

Can you post your layout file ?

 

[RichardN]

I believe 'Width' is a reserved word. Try another variable name.

Violations of reserved words can be very difficult to debug..... as the error you get does not always give a clue to the error the compiler has experienced

 

[LucaMs]

I believe 'Width' is a reserved word. Try another variable name.

The suspicion was legitimate but no, I tried (B4J) and it isn't.

 

[FrankDev]

'Klaus' example works with width
