I tried to open an old project I once started to test using SynEdit. It does compile and work, but when trying to see the form I get an messages of not installed components. In fact the "sysEdit" tab that is described in the Wiki is not seen in the Lazarus IDE. How to activate it ?

Thanks,

Check if you installed syneditdsgn package.

In the "Install/Uninstall Packages" menu in the "Installed" Window there is "SynEditDsgn". But other than "SynEdit 1.0" same features a small green "+". No Idea if this is an error indication. In the "Package Info" it nonetheless says "not installed" (contradicting to it's being listed as "installed" ????).

Doing "use" in the "open installed packages did the trick: now the SynEdit tab is shown. :-)

(Regarding Packages there seems to be some ambiguity with "installed" "used" and "loaded". )

Thanks a lot !

Yep, perfect !

So seemingly the green cross should mean "not used". Great but doubleclicking moves it to the uninstalled list and there seems no means in the "Install/Uninstall Packages" menu to make it "used", or take you to the menu where it can be set to "used" (and the IDE be recompiled).

And with that the text in the Package info window in the "Install/Uninstall Packages" menu it should not read "not installed" but "not used".

(Using the current svn version of Lazarus.)

The "Installed" was misleading. I changed to "Install".

The term "used" in this dialog is somewhat difficult, because there are two sets of "used" IDE packages: The currently running and the future (used when the IDE is rebuilt).
The left side (install) lists the future "used". Packages with a green cross are new, i.e. not yet running packages.

Great but doubleclicking moves it to the uninstalled list and there seems no means in the "Install/Uninstall Packages" menu to make it "used", or take you to the menu where it can be set to "used" (and the IDE be recompiled).

The dialog is simple: left side will be installed. Some packages of the right might be installed automatically due to dependencies.

Yep. But if there are some that have a green cross (meaning "known" but not used/intstalled, as said SynEditDsgn claims: "Current state: selected for installation, not installed, RunAndDesignTime" ) the "save and rebuild" button is deactivated and so I can't make them "used" (or installed) in this dialog.

(BTW.: this situation is triggered by "make clean all" for Lazarus.)
