A new style-list% object is created for the new editor. See also get-style-list and set-style-list.

The selection in a pasteboard can be changed by the system in response to other method calls, and such changes do not go through this method; use on-select to monitor selection changes.

To change a large collection of snips from one style to another style, consider providing a style<%> instance rather than a style-delta% instance. Otherwise, change-style must convert the style-delta% instance to the style<%> instance for every snip; this conversion consumes both time and (temporary) memory.

When a style is provided: The editor’s style list must contain style, otherwise the style is not changed. See also convert in style-list%.

The content of an editor can be changed by the system in response to other method calls, and such changes do not go through this method; use on-delete to monitor content deletion changes.

See Cut and Paste Time Stamps for a discussion of the time argument. If time is outside the platform-specific range of times, an exn:fail:contract exception is raised.

Default implementation: Copies the current selection, extending the current clipboard contexts if extend? is true.

See Cut and Paste Time Stamps for a discussion of the time argument. If time is outside the platform-specific range of times, an exn:fail:contract exception is raised.

Default implementation: Pastes.

The x and y arguments are in editor coordinates. If after is not supplied, the frontmost snip at x and y is returned, otherwise the frontmost snip behind after is returned. If after is a snip that is not in the pasteboard, #f is returned.

The result is only valid when the editor is displayed (see Editor Structure and Terminology). Editors are displayed when get-admin returns an administrator (not #f).

The first result is the x-coordinate of the center and the second result is the y-coordinate of the center.

See also interactive-adjust-resize.

Default implementation: A negative value for either x or y is replaced with 0.

The actual mouse coordinates are first sent through interactive-adjust-mouse before determining the locations passed into this method.

Default implementation: Does nothing.

Snip locations in a pasteboard can be changed by the system in response to other method calls, and such changes do not go through this method; use on-move-to to monitor snip position changes.

The selection in a pasteboard can be changed by the system in response to other method calls, and such changes do not go through this method; use on-select to monitor selection changes.

• Clicking on a snip selects the snip. Shift-clicking extends the current selection with the snip.

• Clicking in the space between snips drags a selection box; once the mouse button is released, all snips touching the box are selected. Shift-clicking extends the current selection with the new snips.

• Double-clicking on a snip calls on-double-click.

• Clicking on a selected snip drags the selected snip(s) to a new location.

• Clicking on a hiliting tab for a selected object resizes the object.

The editor is internally locked for writing when this method is called (see also Internal Editor Locks). Use after-delete to modify the editor, if necessary.

Default implementation: If snip accepts events, it is designated as the caret owner and all snips in the editor are unselected.

Called before a snip is inserted from the editor, after can-insert? is called to verify that the insertion is allowed. The after-insert method is guaranteed to be called after the insert has completed.

Note that a snip calls resized, not this method, to notify the pasteboard that the snip resized itself.
