Text Gadget and no variable

Hello Polo.
Actualy, a variable is associated with a textgadget. If I remove this variable in the gadget inspector, I have this form.
Code: Select all
Procedure OpenMainForm(x = 0, y = 0, width = 600, height = 400)
OpenWindow(#MainForm, x, y, width, height, "", #PB_Window_SystemMenu)
= TextGadget(#PB_Any, 40, 50, 100, 25, "My TextGadget")
EndProcedure
Is it possible to create a textgadget (or combogadget) without variable?
Thank.

Every Gadget in PB needs an ID. The Visual Designer offers two ways (the same like manual coding...) for that:
- Constants
- #PB_Any in combination with variables
Uncheck the Checkbox "#PB_Any" in the Gadget properties an set a name for the constant and all is fine.
Code: Select all
Enumeration FormWindow
#MainForm
EndEnumeration
Enumeration FormGadget
#txt
EndEnumeration
Procedure OpenMainForm(x = 0, y = 0, width = 600, height = 400)
OpenWindow(#MainForm, x, y, width, height, "", #PB_Window_SystemMenu)
TextGadget(#txt, 40, 50, 100, 25, "My TextGadget")
EndProcedure
You can change this behaviour as default also in the options.

Hello mhs.
Forgive me, but why use a variable that has no use?
I have a preference for this code.
Code: Select all
Enumeration FormWindow
#MainForm
EndEnumeration
Procedure OpenMainForm(x = 0, y = 0, width = 600, height = 400)
OpenWindow(#MainForm, x, y, width, height, "", #PB_Window_SystemMenu)
TextGadget(#PB_Any, 40, 50, 100, 25, "My TextGadget")
EndProcedure
It is functional

If you uncheck the option
#PB_Any then
no variable is used for that gadget.
Instead, a constant is used, which has no consequences on memory, performance or something like that. It's just a number and don't hurts.
Somewhere the visual designer must have its limitations, he can not please everyone.

I can see why in some situation keeping the pointer is not necessary, although the form designer is made to keep track of each gadget's id or pointer so I'm afraid it will remain as it is.
