Previously the value of the SpinBox is re-evaluated after every change
to the TextBox control. This leads to very unintuitive behavior such as
the user deleting the contents of the box and it having no
visible effect. This happens because the TextBox no longer has a valid
number and so gets reset to the current m_value of the SpinBox.
By defering the update of to the SpinBox value until focus leaves the
control we provide a much more intuitive experience with the text box.
We do still validate when a user types something that it parses to an
int. If it does not we delete the most recent character. This in effect
prevents non-numeric numbers from being entered.
Upon losing focus the value will be checked. If empty we set the SpinBox
value to the minimum allowed value.
With a new DragCopy cursor icon being used on accepted events, this
caused a 'false assumption' that everything can be dropped into
AbstractView.
This will now only happen if the View is editable, which still isn't
perfect, but at least the Settings app will no longer change cursors.
Also note that we won't get "drag move" events as the comment below
says, which disables automatic scrolling when dragging an element.
... 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.
