Continuing with some usability fixes... Here's a fix I guarantee that we will *all* appreciate, for the Arranger, PianoRoll, DrumEditor, and /especially/ for those who work with WaveEditor:
Zoom about the cursor! The Zoom In and Out shortcuts Ctl+PgUp/PgDown (defaults) and Ctl+MouseWheel now zoom about the mouse cursor position. Until now, all zooming was done relative to the canvas' left edge. I can't tell you how many frustrating years I've worked with wave parts in MusE, where one frequently needs to zoom in and out from low to high magnification just to find those unwanted spikes or do some fades or curious viewing or whatever. Since the zooming was relative to the left canvas edge, we would zoom and our reference position would go whipping waaaay to the right leaving us completely lost - "where the heck am I?" - and adding insult by forcing us to do a long painful squint-eyed scroll back to the place we were looking at. At high magnifications, this was hell. No more. Be gone! Mag... ...nificant! Try 'er out. Note that due to the fact that MusE does not allow the left edge of a canvas to "pull in" ie does not allow bar zero to be "anywhere", when you cross over the threshold of the horizontal scroll bar thumb track being "full" or completely left, you will *lose* the point you are zooming about, as it *must* shift. Not much I can do there. Maybe someday we can allow it, so that you *never* lose you zoom-about point, no matter what zoom level you are at. Also, due to rounding and conversions etc, the zoom-about point may shift slightly as you zoom. It's only worse at higher magnifications. Tim. >From ChangeLog: ------------------------------ Feature/fix: Zoom at cursor! Zoom Ctl+PgUp/PgDown (defaults) and Ctl+MouseWheel now zoom about cursor. Eliminated redundant call in ScrollScale::setMag(), by blocking signals. Consolidated all HorizontalZoomIn and HorizontalZoomOut functions into a single HorizontalZoom. Added eight more 'quick zoom' levels to class ScrollScale. Modified all HorizontalZoom functions to pass cursor offset, and use it in ScrollScale::setScale(). ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
