Hello,

This is my first post here, sorry if it's not the right place.

Two months ago i downloaded Lazarus and immediately enjoyed the same
feelings as with my good old Delphi5 20 years ago  . Congrats guys !

I seized the opportunity to write a Notepad clone application with
auto-backup and unlimited undo/redo. Then I added a basic dark theme.

For this I had to specialize TMemo, TOpenDialog and TSaveDialog with
Windows API. I also built a themed scrollbar component linked to the
memo.

I wrote comments & explanations in the source code and created a few
components to highlight the key points.

Here is the full source code (Application + Lazarus components) :

Don't hesitate contacting me for any question/help.

Hello Air16,
Welcome to the forum.

Thank you for sharing your work and components.
Unfortunately I am a Linux user, your NotepadEx needs Windows unit.

Yes the main goal was to clone Notepad and use Windows native 'Edit'
control (= Lazarus TMemo) so I had to use some Windows-specific code.

Clearly the app & components can be easily extended to Linux
(especially the two main features : auto-backup & undo/redo), i'm
waiting for WSL2 GUI feature to do it. I'm afraid I'll need Win11 for
this, and I plan to upgrade when it is completely stable.
