Hello People!

My Lazarus is not the name of the components in Delphi that option as "show components caption," you know someone has a version that has this property?

I'm sorry my english, am brazilian and use Google Translate

Use latest version of lazarus - download snapshot or build yourself from the sourcecode of svn trunk. There this options works.

If your question is "How can I get Lazarus to show component names in the designer?" then (in recent versions of Lazarus) select Environment
Options
The Options dialog has a TreeView on the left with four headings Environment
Editor
Codetools
Debugger

if 'Environment' is not expanded, click on the + sign, then select the subheading
Form Editor

This page has four panels:
Grid
Rubber band
Miscellaneous
Guide lines

The first check box under 'Miscellaneous' is the component caption option.
If I have not understood your question correctly, you'll have to ask it again.

Hi,

A Matrix "Class" that uses operator overloading for nice matrix formulas is now available here:
http://paginas.fe.up.pt/~paco/pmwiki/index.php?n=DynMatrix.DynMatrix It can represent a doubles matrix with any number of row or columns.

It is released under the Modified LGPL version common to the FCL/LCL

Please let me know about bugs, possible improvements and any question.

Best regards,

Paulo Costa

I see your matrix store double type value. Is it possible to write a generic matrix class using FPC class templates (although I never used FPC templates)?

While I think it is possible it doesn't seem a good idea in terms of extra work versus the extra functionality:
I felt for that temptation with my C++ version and the code was ugly, the declarations were ugly and the errors also become ugly. Worse, it doesn't make sense for most types, integer times are not suited to matrix operations like inversion and for the real types, extended is becoming deprecated and the only contenders are doubles and floats.

I did a version using defines to create a float and a double version but found out that I ended only using the double version...
