widget-button-click should use mouse-track

hrvoje, it looks like you're the maintainer of wid-edit. i'm trying to modify about.el so that button1 as well as button2 selects a link. i notice a few problems with wid-edit: 1] it doesn't provide any obvious way of controlling which buttons do what. 2] all of the modal loops in it should be eliminated and rewritten using mouse-track hooks. i originally wrote the mouse-track hooks to be very flexible and allow for multiple simultaneous actions with different mouse gestures -- e.g. selection of text at the same time as doing something on a "click", i.e. down+up without significant movement. last year i extended mouse-track so it will work with all buttons, and changed the default binding of button2 to use it as well as button1. when drag/drop gets implemented, it can entirely be done using mouse-track hooks even if the dragging is to be done with button2. your code in wid-edit tries to do some of the same things, but not so well -- e.g. it doesn't handle text selection. rewriting it using mouse-track hooks will get you these benefits and others for free and make the code in wid-edit smaller and simpler. e.g. you won't have to manually apply mouse-face, glyph up/down, etc. i will gladly help you if you run into any problems with mouse-track in the process of making this change. btw point #1 comes for free if you use the activation mechanism i recently wrote, which sits on top of mouse-track and provides exactly the "do an action upon click" that you implement in wid-edit. -- ben I'm sometimes slow in getting around to reading my mail, so if you want to reach me faster, call 520-661-6661.
