A first attempt at a Style editing dialog.

Notes on CSS selectors

#
ID selector: Selects an object by ID. Example: #MyRect { fill: red; }
.
Class selector: Selects and object by class. A class attribute may have more than one value, e.g. class="button red". Example: .red { fill: red; }
element name
Element (object) selector. Example: rect { fill: red; }
*
Wild card selector. Selects everything. Example: * { fill: red; }

More complicated selectors are possible.

Style dialog

The dialog presents a list of CSS selectors.

Clicking on selector
Selects all matching objects in the SVG document.
Double clicking on selector
Selects all matching objects in the SVG document and opens CSS dialog.
Dragging selector
Allows reordering selectors.
Click on object
Selects all matching selectors.
Modifying property
If "Sheet" enabled: modifies CSS of highlighted selector if only one selector highlighted otherwise produces error message. If "Attribute" selected: modifies inline style attribute.
Clicking on '+' in front of selector
Adds selected objects to selector.
Clicking on 'x' in front of object
Removes object from selector.
Clicking on '+' at bottom
Opens up text entry dialog with a GtkEntry widget to add new selector. If the selector is a Class selector, adds the class attribute to the selected objects with the value of the selector name. If the class attribute already exists, appends the selector name to the class attribute value. If only one object is selected, the entry dialog is prefilled with the object's id.
Clicking on 'x' at bottom
Removes selected selectors unless selector is a Class selector. If it is a Class selector: if the selector was selected by clicking on it, remove the selector; if the selector was selected by selecting objects, removes the selector name from all selected objects class attribute.

This dialog could replace the "Selection Sets" dialog, using CSS class attributes to define sets.

Tests

CSS dialog

A first step would be to implement just entry by text editing. The user would type in "fill: #000000". After hitting return, Inkscape would validate the CSS and update the dialog. Future steps would be to include a drop-down menu of all applicable styles.



An idea for how to organise in the user interface a simple editor for existing css styles which apply to elements:

Not covered:

* Any internal issues with css handling
* Any missing events for updating styles when css changes (not working in 0.48)
* Copy and paste of style when non-inline style is selected
* The editability of external css documents (when supported)
