Hi All,
I’m new to Lazarus and Free Pascal but I’ve been using Delphi since v2.
I’ve got some old Delphi apps that I need to compile for Linux. I’m
using Lazarus v0.9.28.2 beta on openSUSE 11.2 64-bit. The IDE loads
fine and the About box displays normally. However, when I select
File/Open, the open file dialog displays with a blank dialog on top with
Lazarus in the title bar but no text or buttons. I believe it’s trying
to display an error message. When I close this dialog, Lazarus closes.
Any ideas?
Thanks,
Steve
Delphi form definitions are not compliant to Lazarus forms . Therefore
if you try to Delphi sources with some modifications to complete a
compilation successfully it is very likely that you will get the above
results .
My suggestion would be as follows :
(1) If there are computation parts within Delphi form related procedures
such as click_Button_x and others , move these parts into independent (
from Delphi form ) non-GUI procedures as much as possible .
(2) Re-generate your forms by Lazarus and call those independent non-GUI
procedures from your form procedures . Your Lazarus generated forms will
work . If they do not work you may ask help from Lazarus users .
Personally I do not have an exhaustive list of features and variables
one by one comparing Lazarus and Delphi forms and guidelines to complete
different features . The easiest and shortest way is to generate forms
by Lazarus .
Since you have a working prototype in Delphi , such a re-design should
be easy .
Thank you very much .
