Because it's generally the right thing to do, and server grabs broke
badly with input devices / client side windows.
gimpdisplayshell-grab.c: change logic to only server-grab if an event
is passed to the pointer grab/ungrab functions, but always use
gtk_grab_add/remove() which is sufficient in most cases.
gimpdisplayshell-tool-events.c: have the grab functions grab the
server only for space-bar scrolling and do all tool interaction,
including ruler clicks, with gtk_grab_add/remove(). Refactor things
a bit to also use the grab API for button-2 scrolling.
gimpdeviceinfo-coords.c: transform the event's coords to the canvas'
coordinate system, they might come from a ruler now.
This fixes the following bugs:
Bug 645315 - gimp_display_shell_pointer_grab: gdk_pointer_grab failed...
Bug 644351 - Gimp misses some strokes especially when drawing fast
Bug 645747 - Gimp is now unusable on xfce4
Add a canvas item group for previews, and a small preview infrastructure
to GimpDrawTool, and put the transform preview into the preview group,
which is below all guides, grid and layer boundaries.
This commit only adds the class and removes the members from
GimpDisplayShell, so everything looks more ugly than before, but
I wanted the member moving separate from any refactorings.
and simply *always* set the tool to the right state before sending it
a button_press. GimpTool's state setting functions are now smart
enough to simply ignore setting the same state again. When recieving a
FOCUS_IN, skip state setting when the pointer is grabbed, which is a
safe indicator for tool interaction going on. This hopefully fixes
states for both click-to-focus and focus-follows-mouse *and* fixes the
previously warning case where a new image was opened into an already
focussed canvas (the warning then happened on button press, and the
tool was in an inconsistent state).
And remove all the complicated handling code entirely. This makes
GimpTransformTool a lot less complex. As a nice side effect, the
preview is now always 100% in sync with the grid and handles.
Spit warnings in the functions if grabbing fails and return a boolean
success value. Bail out in the callers upon grab failure instead of
assuming that grabbing always succeeds and running into an
inconsistent state that can cause all sorts of problems.
which is the last bit of non-item drawing of stuff that is not
somehow the image itself... wheee!
This involves reverting commit
6bce0641d4 and adding back all the
vectors handlers that were in gimpdisplayshell-callbacks.c before.
Change the callbacks to manage proxy items for all the image's
vectors.
and use it to draw the layer boundary. Remove a lot of stuff
that was there only to draw the boundary before:
- remvoe all layer boundary stuff from the selection code
- remove gimp_display_shell_draw_layer()
- remove enum values GIMP_SELECTION_LAYER_ON,OFF from core-enums.h
- remove all lines calling gimp_image_selection_control() with
the removed enum values
- remove gimp_layer_boundary()
- Invalidate the proper area when an item gets added or removed.
- Draw the kept canvas items instead of calling a draw tool function.
- The draw tool now sets its item on the shell.
Instead of passing GimpChannelType as mask color to
gimp_display_shell_set_mask(), change that function to accept a
GimpRGB color.
Adapt GimpForegroundSelectTool, the only user of the display mask
feature, to this change.
Instead of blending the scaled image data onto the checkerboard and
then painting this image to the screen, render the image data into
an ARGB cairo image surface. Then paint a checkerboard on the canvas
and the image on top of it.
...just as we do for drawables. Connect to adding, removing, modifying
and toggling visibility of all vectors and emit "update-vectors"
accordingly. Add an update-vectors signal handler to GimpDisplayShell
and remove all other vectors handlers.
Add anchor and spacing parameters to the shell overlay API, so
overlays can be positioned on each side of a point in image space,
with configurable spacing in display space.
This API is most likely not final, but enables adding the vbox of
shell widgets to the image window's vbox *after* the shell constructor
returns. Seems to work nicely :-)
Set the properties when updating title and status. In GimpImageWindow,
connect to notifications of the properties to update window title and
statusbar.
Also move some of their related code and update other code to
go via gtk_widget_get_toplevel(), but also add some horrid temp
/* FIXME image window */ hacks.
Also remove GimpDisplayShell's "window_state" member. Use
gtk_widget_get_toplvel() to get to the GimpImageWindow when we need a
display shell's fullscreen state.
