Set correct padding and size for the palette, window implementation - SL #4144
A new API is provided: PaletteMenuBox is a container to be used in Palette.set_content(). This is to hide the implementation details and set the corresponding paddings and sizes. Usage: box = PaletteMenuBox() palette.set_content(box) Then we can append items to it, like: item = PaletteMenuItem(text_label, icon, xo_color=xo_color) box.append_child(item) separator = PaletteMenuItemSeparator() box.append_child(item) We can also append any widget, and the box will handle the paddings: box.append_child(widget) style.DEFAULT_PADDING for horizontal and vertical padding is the default. But can be overriden: box.append_child(widget, horizontal_padding=0, vertical_padding=0) Details: - move palettemenuitem.py to palettemenu.py - Width of palette: make it a minimun size of 3 Sugar grid cells. - Padding of content, secondary box: we need top and bottom padding, which can be set when packing the items container inside the secondary box. - Padding of menu items: needs to be just for left and right, so move the padding to a new horizontal box. - Padding of separators: unlike GtkSeparatorMenuItem, GtkSeparator doesn't support padding. But we can wrap it in a GtkEventBox and force the height of the widget there. Signed-off-by: Manuel Quiñones <manuq@laptop.org> Acked-by: Simon Schampijer <simon@laptop.org>
