84aab564b4 enable fade-out display by default in A4. 
..because fade outs are implicit in A4.
Eventually the GUI needs to set_show_background_fade() as needed.

7f41de7427 Improve waveview height and scaling. 
The top line of the selection rect is arguably 1 px too low, but
waveviews seem centered on the area properly.

b3fb73812c Position (and size) canvas tooltips such that they better resemble Gtk tooltips 
Mixbus in particular uses both types of tooltip so we might as well make them look the same.

N.B. The appearance is fine now on Windows but needs to be tested on the other platforms (i.e. some tweaking might be necessary).

2234fd4b8a Delete a canvas tooltip after we've finished with it 
All canvas objects share just one tooltip object which is based around Gtk::Label. The Label expands if the current tooltip text is wider than the previous text. However, it doesn't shrink again if the next tooltip has shorter text. Eventually, this results in some very strange looking tooltips (especially in Mixbus where they're used quite extensively).

Deleting the object after use will force a new object to get generated next time (at the correct size). There's still only ever one object per canvas but it's no longer persistent.

2e27b55179 For the canvas library, #include 'gtkmm2ext/gui_thread.h' rather than 'gtk2_ardour/gui_thread.h' 
Technically it doesn't make much difference but from what I can tell, the only files which #include 'gtk2_ardour/gui_thread.h' are the source files from gtk2_ardour itself. The support libraries always #include 'gtkmm2ext/gui_thread.h' directly (which seems sensible). So for consistency's sake, let's keep it the same for libcanvas.

8962bfba61 Better fix for 6183. 
Invalidate all source entries from the image cache when we get our
region's DropReferences signal, while ignoring any subsequent regions with
no source.

86c6541323 Move PC flags to avoid obscuring region name. 
Fixes bug #6179.  Top vs. bottom seems pretty arbitrary to me, and this solves
the obscuring issue (which is quite common since there are often PC events at
the start of MIDI files), so bottom it is.

e7b0e67bc8 Manual merge of the drawing component of waveview branch. 
In summary:

    * no antialiasing of waveviews
    * no diagonal lines
    * simplify clip detection
    * don't use LINE_CAP_ROUND for outline
    * use the wave colour when drawing outline only

Ben Loftis
b8ec035b24 _single_exposure is now a member variable for each GtkCanvas. 
Gtk coalesces multiple exposes into a single combined rect.
If _single_exposure is disabled, we break apart the individual expose rects for the canvas rendering.

c679d616f6 correct drawing of rectangle borders. 
They need to use fractional coordinates, and the border position needed
generalizing for other border widths. See verbose comment for details

b4a0136155 tweak to help with uncoalesced renders 2015-02-03 17:35:37 -06:00
Paul Davis
9fab39358a render canvas using the GDK region rather than the GDK area. 
The region is the un-coalesced set of rectangles that were requested for redraw. The area
is the coalesced single rectangle. In the worst cases, the coalesced rectangle could span
the entire window even though just two pixels in opposite corners were to be redrawn.

There is a problem with the verbose cursor as it is dragged across MIDI tracks. TO BE
FIXED.
