Sorry, but you can't control the core UI from a plug-in.

Yes.

The answer is: it is not possible at the moment. Sorry for that.

A plug-in can itself use the tools, , but it can't change most things in the UI context.

How to change the active current tool from a plugin?

I am a little worried about what you said. I can change colors with gimp_context_set_default_colors (void); (and it works) but I don't manage to use the gimp_context_set_paint_method (const gchar *name); method. I tried this code gimp_context_set_paint_method("gimp-paintbrush");

If I can't change the paint method from my plugin, what is the aim of those methods ?

You can change the context that your plug-in is running in. By default that's the user context but that's just for historical reasons. Actually you are supposed to use gimp_context_push() before you use any methods that alter the context.

If I can't change the paint method from my plugin, what is the aim of those methods ?

The paint-method is not reflected anywhere in the UI. It only affects paint operations done through the PDB.

May I ask why you want to change the tool from your plug-in? That doesn't sound like something a plug-in should be doing and I am curious as to why you think that it would be useful to be able to do that.

Sven you look like a hardworker, thank you so much for answer so quikly! That I told I try to design an edge detection plugin. This plugin helps the user to select an objet on a picture. In first the user select one algorithm (like Sobel for example), next the plugin will create 3 layers: -a copy of the picture to enable the user to fill gaps that block the edge detection
-a white picture where the result of the algorithme appears -a flag layer where the user can draw "in" area and "out" area

the most is done, only the flag must be finish. I would provide flag 's buttons in my plugin that: -select automaticly the flag layer (ok no problem) -active the paint brush tool (the problem!) -select apropriate color(green for "in" area and red for "ou" area)(an another problem)

if you have any secrets gimps tips for help me it'll be wellcome

Hi Laurent,

In the GIMP architecture, things that require the user to interact directly with an image, by painting or any other use of the mouse, must be implemented as tools (in the core) instead of plug-ins. You could look at the code for the new Foreground Select tool, which seems to have some things in common with the tool you are trying to create.

There has been some talk of pluggable tools, but this is currently an idea for the future.

Best wishes,

-- Bill
