But we can imagine an environmental variable that tells where Gambas is installed, without relying on a symbolic link. This will solve the first problem. But now you must have all shared libraries directly or indirectly used by Gambas on your USB disk, which may be huge. To know them, you must run "ldd" on each shared library of each component used by your project. And you won't be able to run Gambas executables directly as they find the interpreter with "#!/usr/bin/env gbr2", but by changing the PATH variable so that the gbr2 symbolic link on the USB disk is found first, it will run! I will tell you when I make the environmental variable change. His name will be something like GB_DIR, or GB_ROOT. > > Another questions: > 1) May I create proprietary (not open-scource) gambas2-applications and > components for gambas2? > It depends on the license of each component you use. For example, you can't if you use Qt3.

The sentence means: "You should use the Data event handler if you have thousands of rows to display." (I fixed it in the wiki). Instead of explicitely setting the GridView cell contents, just write event handler for the "Data" event, so that data is filled on demand. The Data event is raised each time the GridView needs the contents of one cell. > > 3) When I hide persistent Form, how to display it again? > Show() ? > 4) On my monitore with resolution "1024x768" Forms and widgets on them > look great.

Indeed. I never use it, so I didn't implement it. I will put that in my TODO file.
