How to translate a Delphi7 proj to Lazarus 1.6??
lazarus / 67-Windows

Hi,

I found that some parts, which I used very often in Delphi7, cause now
programs if a migrate to Lazarus  .
E.g. I need to remove Windows stuff like printer setup dialogs,
messagebeep, winexec, etc. This is expected, and often easy because I
can simply comment these things out.

BUT, what about things placed in formulars, like a component gfvcl
which gave me a gradient fill in Delphi?
Or how to change a spinbutton to updown component of Lazarus?

The problem is that Lazarus simply does not open the forms. It would
be good to instruct Lazarus just to skip reading-in such Windows-
Delphi-specific stuff, but how?
What would also help is a text view for formulars, like in Delphi.
Then I could edit within this text view. But I have not found such
feature in Lazarus yet.

Any hints are highly welcome, thanks!

Bye Stephan

Use the Delphi project converter first, then start working from the
converted source. 3rd party components will of course need to be
ported if not already (or magically) done.

Check for all used Componets (3rd party and from Borland inkluded) if
they exists in Lazarus. And look for the alternatives (eg. Ports) in
Lazarus. If you use DB-Komponents, try to replace this in Delphi with
Zeos.  

If you find ported Componnets, try to use this first in Delphi, then
make the port to Lazarus,
