Hello, I am just trying Lazarus and find a bug with form inheritance when the parent form contains frame.
Here is the step to produce it: 1. Create a form Form1 2. Create a frame Frame1 contains a button 3. Place Frame1 onto Form1 4. Create form Form2 descended from Form1 through File -> New .. -> Inherited Items 5. Change something on Form2 like repositioning the frame. Compile and run, when Form2 shows up an error message will be poped up: Project raised exception class "EComponentError" with message: Duplicate name: A Component named "Frame1_1" already exists. The problem lies in the lfm file which generated as follows: inherited Form2: TForm2 Left = 452 Top = 67 Caption = 'Form2' inline Frame1_1: TFrame1 ==> HERE IS THE BUG Left = 48 Top = 96 Visible = True inherited Button1: TButton end end end if I change "inline Frame1_1: TFrame1" to "inherited Frame1_1: TFrame1" everything goes well. However, there are still some problems: 1. I can't display the .lfm file as Form, lazarus complains class TFrame1 is not found. Manually adding Frame1 to uses clause of unit2.pas solves the problem. 2. As soon you change anything in Form2, the "inline Frame1_1: TFrame1" always comes back again. I am using Lazarus 0.9.26.2 on Windows XP. Is this a known bug? -- Bambang P _______________________________________________ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
