Reordering components in HPanel fails

[Stéphane Aulery <lkppo@xxxxxxx>]

Hi,

I try to clone AstroGrep under Linux

https://astrogrep.sourceforge.net/pics/ss_main_new.png

I'm having trouble with the layout. I can't get the fields to stretch 
horizontally. I guess I'm not using the right combination of containers 
and options. Maybe you can advise me on this (I'll provide a screenshot 
this evening).

For the moment I tried to put ComboBoxes and Labels in an HPanel, itself 
in the left part of a Splitter. I use the HPanel because it 
automatically arranges the fields.

My problem is that if I arrange the fields with the graphical editor or 
try to order them with the container tree viewer, I never get the 
controls in the order I want. If I reorder the fields in the container 
tree viewer and then save, the order is lost.

I don't understand what order it follows unless it's the initial 
insertion order of the components, which is no use to me since you can't 
define an Order property.

What am I doing wrong?

Regards,
