[Development] Forum Discussion Page for 'mouse shortcuts'

[Rick Stockton]

Final design and subsequent coding in Qt, starting in about a week.

I have created a Qt Devnet forum Thread for work on Mouse Shortcuts. 
It's at http://developer.qt.nokia.com/forums/viewthread/12843

Right now, it's only got my initial post, which proposed code based on 
the same scheme as keyboard shortcuts (QKeySequence, QshortcutEvent, and 
QShortcut working with Qt signals and slots.) In my SIMPLE design, there 
will be 3 ways to invoke a mouse-based shortcut: mouse button click, 
button doubleclick, or holding one button down while clicking a second. 
You will not be able to mix keyboard keypress events and mouse button 
events together as a shortcut invocation sequence. (Invocations will 
consist of QKeySequence sets on the keyboard, OR mouse button actions -- 
not the two together.)

You will be able to execute the same shortcut Action by performing 
alternative invocation sequences on the two devices. The 'Back' Shortcut 
Action, for example, can be invoked by either 'Alt + left' on the 
keyboard, OR the back button on the mouse, in a KDE or GNOME 
environment. (As Qt-provided defaults.) And of course, KDE will 
ultimately have a "configure your mouse shortcuts" module with all the 
bells and whistles which are now present in 'KHotkeys'. ('Global' 
shortcuts versus 'Application' shortcuts, etc.).

I will attempt to do one special keyboard interaction: For 
accessibility, KDE has been asked to provide a way to toggle mouse 
modifier keys from the mouse. (Allowing a person with only one hand, or 
with ZERO hands, to move his/her 'clicker' device over the the keyboard 
slowly.) This would be in Qt, as a very fast, low level operation: Check 
if a mouse-based modifier has been set to 'pressed', and if so, set thge 
corresponding modifier Bit before passing keyboard events upwards.
