 Posted: Mon Feb 13, 2006 4:03 pm Post subject: Switch betweem two dfm files |
 |
|
Dear readers,
For some project I need to have two apearances of the same dialog.
Currently I have a file HandleDlg.dfm which defines how the dialog looks
like.
And I have a file HandleDlg.pas which defines how the dialog behaves.
Is there a simple way that I can have an extra dfm, say FancyHandleDlg.dfm,
which shows the dialog a bit different, and switch in code which appearance
to use.
Otherwise I have to duplicate *.pas as well. Which appears a bit silly, but
will work.
Please advice, Jean. |

The VCL (and the IDE) requires that the DFM file for a form has the same
filename as the unit it belongs to. What you can do, however, is to create a
base class for the dialog that implements the common behaviour with the common
controls (or none), then derive two new form classes from this base class,
using visual form inheritance. These two classes each have their own DFM file.

Look at CreateNew and ReadComponentResFile in the help.
