I had to add a set_title(String) helper function for ImageEditor because
TabWidget requires it. This is a temporary fix and will be handled in
subsequent commit.
Per-channel values of the pixel color are now displayed in the status
bar when the PickerTool is selected. This information obviously updates
on mousemove.
This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.
This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.
This causes the corner X to correctly have dots when any of the open
tabs have unsaved changes. Event calls and undo stack modifications
have been collected to one spot.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Refactored PickerTool functionality to the ImageEditor level and added a
flag to Tool Base Class to allow for tools to override Alt+Click
ColorPicker functionality
The Undo/Redo actions now tell you what kind of action will be
undone/redone. This is achieved by adding an "action text" field to the
ImageUndoCommand and having everyone who calls did_complete_action()
provide this text.
We often want to zoom and fit the content of the widget into the
visible frame (or some rect within the frame), and it makes sense to
move this functionality into the AbstractZoomPanWidget to minimize
the amount of coordinate math derived classes need to do.
This commit moves the code that implements this functionality from
`PixelPaint::ImageEditor` into `AbstractZoomPanWidget` so that we
can also use it for other applications (such as ImageViewer!)
The ImageEditor tracks whether it was loaded from an image
(the alternative being a project file.) If it was loaded from an image
file we redirect save project actions to save as instead.
This allows us to request any specific editor to close itself. Earlier,
this could only be done for the currently active editor, so trying to
close inactive tabs would not work properly.
Previously the save logic was hardcoded to only work for the active
editor, so closing editors in the background would not properly
handle the unsaved changes. This patch brings us closer to be able
to fix that problem.
As noted in the latest hacking video, it doesn't seem to make much
sense to store the title and path in the image itself. These fields
have now been moved to the actual ImageEditor itself.
This allows some nice simplicfications, including getting rid of the
`image_did_change_title` hook of ImageClient (which was just a way to
report back to the editor that the title had changed).
This just allows us to ask the image editor to update the tool's
current cursor. This is useful in cases where a tool may want to
change it's cursor for some operation, and wants to invalidate the
active cursor cached in the ImageEditor.
Depending on the size / scaling of the UI, someone might want to
change what the threshold is to show the pixel grid. For instance
if you are working on a 50x50 image, and want to see the grid while
still fitting the whole image in the editor.
Since there's no UI for settings in PixelPaint right now, this
commit just uses LibConfig to read the following entry:
("PixelPaint", "PixelGrid", "Threshold")
which is then used when drawing the grid.
This is a feature I missed from Photoshop: it sets the scale and
position so that the image fits (it's longest dimension) into
the editor view. There's a 5% border left around the image to
provide context. This is just arbitrary seemed like the right
amount after some trial and error.
The ImageEditor knows more about the image than Image itself. So to save
a project with all the information known to the program about an image
it's logical that ImageEditor performs that task rather than the Image.
There isn't any additional data added yet, but now there's the
possibility to do so.
This also required adding a new hook to `ImageClient`, since there
wasn't a way of telling the ImageEditor that the full rect of the
image has changed (as when we rotate).
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.
