[Gambas-user] Crssed interexchange between forms

[Richard]

As an alternative to Rob's suggestion that you make all form controls public 
(which should work) you might prefer to create public methods on your forms 
which will take a parameter from the calling form code and store the value in 
a now local form control property.

For example; if on frmCW you have 

PUBLIC SUB Write_CWcall_text(calltext as string)
	CWCall.text = calltext
END SUB

then on FMain you would write

	 IF cw_on THEN FrmCW.Write_CWcall_text(Call.Text)

That should also do the trick and preserve flexibility. If form controls are 
public then you can write directly to them from ANYWHERE. What if you decide 
to change the control from a text box to a value box? You would have to go 
through all your code and change all the writes and reads involving the 
changed control. 

If instead you do it as I suggest, then you only need to change the access 
methods for READ and WRITE in one place. Much easier, yes?
