The following Tutorial was found on the
Ubuntu Forums and was written by
MetalMusicAddict. I claim NO credit for this tutorial.
This is for the people who are used to this feature in Photoshop but everyone who uses The GIMP could find this usefull.
-This HOWTO involves using a wheelmouse. If you dont have one this still should help you to assign a keyboard action. Ill work on that and add it later. So far Ive tried this on Windows, Ubuntu, a desktop and a laptop. All worked for me.
1. Create a new brush by going to
File->Dialogs->Brushes.
2. Once the
Brushes dialog box is there at the bottom, click on the
New Brush option.
3. Give the brush a name.
Dynamic is what I call mine.
Your settings should look something like the pic below to start.
As you learn, change 'em as suited.
4. Open the
File menu then go to
Preferences.
5. Select
Input Controllers.
6. Select tab
Main Mouse Wheel.
7. Make sure the
Enable this controller box is checked.
8. Assign a preferred
Action to your mouse
Event. You will find the actions under
Context in the popup dialogue when you click on
Edit to edit your
Event.
ie: I have assigned the
Scroll Up (Control) event to
context-brush-radius-increase action. Respective,
Scroll Down (Control) is assigned to
context-brush-radius-decrease.
So now by holding the
Control button and scrolling the mouse wheel
Up or
Down I can dynamically change the size of the brush.
Now you can resize on-the-fly your brush, pencil and eraser. Funny how the answer to alot of peoples post was built in.
The 1 thing Ive seen is that you will only
see the brush resize if you hover over your image but the window is not focused.
Not the same as PS does it but still very nice. And remember, The GIMP isnt PS.

Tha is the end of his tutorial. In addition to it you can also set the
Scroll Up (Alt) event to
context-brush-hardness-increase action. as well as the
Scroll Down (Alt) event to
context-brush-hardness-decrease so that you can change the hardness of your Dynamic Brush whilst holding the ALT key.
