... instead of in the center of the cursor bitmap.
It doesn't make much of a difference, as the default cursor hotspot is
center. But since now we switch between a normal Drag cursor and
DragCopy one that has set hotspot, this caused the overlay to shake.
Previously, the cursor would use a default cursor on window frames such
as the title bar and menu bar, which was not quite correct as drop
events were still handled there.
Layer::erase_selection used to erase the entire bounding box of the
selection. With the add/subtract merge modes for the selection tool it
is possible to create selections which are not rectangular. This leads
to deleting pixels that were not selected.
This change adjusts the erase behavior to walk the selection rect and
check if a pixel is selected or not before deleting.
Wand Selection tool uses similar logic to the Bucket Tool. Flood filling
and threshold calculations to determine the affected area just in this
case we do not set the pixels of the selected area, instead we use
those pixels to alter the selection mask.
In the future we can probably abstract out the shared flood logic so
both tools can share the code.
Before, the warning dialog would be opened after the NewProjectDialog,
leading to focus-fighting by the two windows. This fixes that and makes
the action more consistent with the standard serenity way of handling
unsaved changes by asking before the NewProjectDialog is brought up.
The way this is achieved avoids having to rewrite open_project as well.
This commit fixes a crash that would occur due to an unnamed file being
automatically saved via EditorWrapper::save(). Now, we throw up a
FilePicker::get_save_filepath.
SDL2 applications are prone to reinitializing the SDL components when,
for example, changing the display resolution. This would lead to
crashes since we were doing things in the wrong order.
* We now decouple `GLContext` from `SDL_Window` a bit more, allowing
the window to be destroyed before the GLContext.
* Do not quit the `GUI::Application`, let our event loop handle exiting
These changes allow changing the display resolution in the Quake3 port.
Specializing point_position_to_preferred_cell for the
RectangleSelectTool as it selects a new cells with a rounding
behavior instead of a flooring behavior
This is done to allow querying the current active tool inside the
event_with_pan_and_scale_applied and event_adjusted_for_layer
functions without risking a null pointer dereference
This method is used to point a position at the preferred pixel of
the image. Certain tools may want to specify a different preferred
pixel for the same input position.
When the location currently displayed in FileManager is removed, find
the nearest existing parent path and open it in the window.
Without the fix, the FileManager window remained in the deleted
directory.
Changing the path in 'DirectoryView' object will automatically update
other components in the FileManager (breadcrumb bar, directory tree
view).
This commit fixes FileSystemModel behaviour when the root path of the
model has been deleted.
In this case, the model index resolved for the root path is invalid and
passing it to 'begin_delete_rows' would trigger assertion failure.
Instead of deleting all children rows one by one, we simply invalidate
the whole model.
And adjust some GML properties. Since a808cfa, splitters grow
opportunistically. Setting them to fixed sizes now quite literally
fixes them in place. Fixes immovable splitters missed in the
aforementioned commit.
Before of this patch, we supported two methods to address a boot device:
1. Specifying root=/dev/hdXY, where X is a-z letter which corresponds to
a boot device, and Y as number from 1 to 16, to indicate the partition
number, which can be omitted to instruct the kernel to use a raw device
rather than a partition on a raw device.
2. Specifying root=PARTUUID: with a GUID string of a GUID partition. In
case of existing storage device with GPT partitions, this is most likely
the safest option to ensure booting from persistent storage.
While option 2 is more advanced and reliable, the first option has 2
caveats:
1. The string prefix "/dev/hd" doesn't mean anything beside a convention
on Linux installations, that was taken into use in Serenity. In Serenity
we don't mount DevTmpFS before we mount the boot device on /, so the
kernel doesn't really access /dev anyway, so this convention is only a
big misleading relic that can easily make the user to assume we access
/dev early on boot.
2. This convention although resemble the simple linux convention, is
quite limited in specifying a correct boot device across hardware setup
changes, so option 2 was recommended to ensure the system is always
bootable.
With these caveats in mind, this commit tries to fix the problem with
adding more addressing options as well as to remove the first option
being mentioned above of addressing.
To sum it up, there are 4 addressing options:
1. Hardware relative address - Each instance of StorageController is
assigned with a index number relative to the type of hardware it handles
which makes it possible to address storage devices with a prefix of the
commandset ("ata" for ATA, "nvme" for NVMe, "ramdisk" for Plain memory),
and then the number for the parent controller relative hardware index,
another number LUN target_id, and a third number for LUN disk_id.
2. LUN address - Similar to the previous option, but instead we rely on
the parent controller absolute index for the first number.
3. Block device major and minor numbers - by specifying the major and
minor numbers, the kernel can simply try to get the corresponding block
device and use it as the boot device.
4. GUID string, in the same fashion like before, so the user use the
"PARTUUID:" string prefix and add the GUID of the GPT partition.
For the new address modes 1 and 2, the user can choose to also specify a
partition out of the selected boot device. To do that, the user needs to
append the semicolon character and then add the string "partX" where X
is to be changed for the partition number. We start counting from 0, and
therefore the first partition number is 0 and not 1 in the kernel boot
argument.
