Very simple question

[wb]

There are 2 forms, I want to load form2 by button on form1, I tried to use Form2.show;, but it gives me "Error: Identifier not found "Form2"
This worked in Delphi..

Compare the uses clauses of your Delphi app and your lazarus app.

Uses unit2 must be in unit1. (or something like that).

There are 2 forms, I can use the "uses" clause so that the first form can access to the other, but in it is not possible to make this in both directions.

(Fatal: Circular unit reference between Unit 1and Unit2

Is there a solution?

There are 2 forms, Unit1 says

Code: [Select]

Form2.Show; Form1.Hide;
When Form2 is closed by user, Application doesn't end, Form1 is still the "MainForm" and keeps running, but hidden.
I tried

Code: [Select]

Form2.Show; Form1.Close; but then the application ends immediately?!

Thanks a lot for your advice

Is there a solution?

Yes, put your uses clause on the implementation part of the unit.

Code: [Select]


unit unit1;
(...)
implementation
uses unit2;
(...)


Code: [Select]


unit unit2;
(...)
implementation
uses unit1;
(...)


Application ends every time you close main form.
