Package Configuration

[PeterX]

Hi all,

I just installed a package, and was wondering where to find the new component.
After searching a while, I found it in MISC.  But why ?

I appended a screenshot, the field marked with a blue frame is empty.
Does a component by default go into MISC ?

When pressing the HELP button, I get the "IDE Window: IDE Options Dialog" website

Code: Pascal  [Select][+][-]

1. http://wiki.lazarus.freepascal.org/IDE_Window:_IDE_Options_Dialog

which does not help ..

There is no default page where components added to the component palette are placed.

A design package will include a Register procedure for the components that get installed.
This in turn uses the standard RegisterComponents procedure:

Code: Pascal  [Select][+][-]

1. procedure RegisterComponents(const Page: string;
2.   ComponentClasses: array of TComponentClass);    

where the Page parameter is a string (such as 'Misc') where the installed component is placed. This string is chosen by the package developer, and if s/he is any good they will document which page is used. If Page is blank ('') the component is not installed at all.

This is the content of the Package PAS file

Code: Pascal  [Select][+][-]

1. { This file was automatically created by Lazarus. Do not edit!
2.   This source is only used to compile and install the package.
3.  }
4.  
5. unit MultiFramePackage;
6.  
7. interface
8.  
9. uses
10.   MultiFrame, ChildFrame, LazarusPackageIntf;
11.  
12. implementation
13.  
14. procedure Register;
15. begin
16.   RegisterUnit('MultiFrame', @MultiFrame.Register);
17. end;
18.  
19. initialization
20.   RegisterPackage('MultiFramePackage', @Register);
21. end.    

I expected there would be a category "MultiFramePackage" afterwards.
But the component appears in MISC (the next one after SYSTEM in the component palette).

Oh .. yes .. found now .. 

Code: Pascal  [Select][+][-]

1. procedure Register;
2. begin
3.   RegisterComponents('Misc',[TMultiFrame]);
4. end;
