This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:
- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
the top margin, the second argument to the left and right margins,
and the third argument to the bottom margin.
Previously the argument order for Margins was (left, top, right,
bottom). To make it more familiar and closer to how CSS does it, the
argument order is now (top, right, bottom, left).
This adds on_tool_activation() to Tool which GuideTool can use
to show guides, if they're hidden, when it's activated. Also
show guides on mousedown since there's no use in drawing invisible
guides.
Tightening of the update rect when firing the marching ants timer
unfortunately meant that only finalized selections would be redrawn,
and any new selection drawn outside of the update rect would not
update.
This adds support for the Tools in PixelPaint to use different cursors
within ImageEditor. For now most of them get the crosshair cursor since
it's the most fitting, but in the future we will want to add custom
cursors.
This tightens the update rects for EraseTool, BrushTool And the marching
ants update in Selection. Inflate Selection update rect by 10x10 to
avoid misalignment when zoomed out.
Previously using PenTool while zoomed in could cause rendering glitches
since the update rect was misaligned with the image, most likely because
of rounding errors.
Loosening the rect with 1 pixel on either side takes care of this.
This patch adds the logic for the GuideTool. Pulling in from outside the
image creates a new Guide, moving a Guide outside of the image deletes
it and a Guide can be deleteted via the context menu.
A Guide is considered clicked when the cursor is less than 20 pixels
away from the line.
Previously changing tools while simultaneously using a widget like a
slider would result in a event_dispatch() failure.
Instead use a StackWidget to set the active widget.
This adds a tooltip to all the slider properties showing their
current value. Previously there was no indication of what
value they had. Also rename the SprayTool property 'thickness' to
'size' like BrushTool calls it.
Applications previously had to create a GUI::Menubar object, add menus
to it, and then call GUI::Window::set_menubar().
This patch introduces GUI::Window::add_menu() which creates the menubar
automatically and adds items to it. Application code becomes slightly
simpler as a result. :^)
AK's version should see better inlining behaviors, than the LibM one.
We avoid mixed usage for now though.
Also clean up some stale math includes and improper floatingpoint usage.
Previously m_constrain_angle could end up not being reset if the
keyup-event was lost, for example when opening a dialog. Instead check
the modifiers in on_mousemove().
This makes sure that scroll_into_view is not called when not necessary,
or when m_layers is empty, which previously caused a crash upon
removing the last layer.
This makes the brush tool start drawing a point before the user moves
the mouse, like in Photoshop and Gimp. The number of iterations of
draw_point makes for roughly 4 clicks to full opacity.
