Change Details

Status: Currently the tools add, substract, paint and wipe have the option to invert their behavior by pressing "CTRL". This is also visualized by a change of color. But the change of state (and color) is only done, when the mouse is moved. Reproduce: - Uses a named tool. - Stop movement - Press CTRL - The color does not change and if you release the mouse button without movement, the non inverted state will be applied. Reason: The state change is triggered as a modifier of the mouse events. So if the mouse is not used, the CTRL press or release is not communicated to the tool. What is needed: 1. We need to extend the event mapping of the state machine. It knows Keypress (but only for non modifier keys), but you cannot get an event on key release, which would also be needed. 2. We might not be able to use CTRL (or other modifier keys); may be "space" in an option.
