Detailed Description

Anything related to Dillo Widget styles is defined here.

Overview

dw::core::style::Style provides some resources and attributes for drawing widgets, as well as for parts of a widget (e.g., dw::Textblock uses styles for its words). Creating a style is done by filling a dw::core::style::StyleAttrs with the attributes and calling dw::core::style::Style::create:

// ...
styleAttrs.foo = bar;
// etc.
style = dw::core::style::Style::create (&styleAttrs, layout);
// do something with style
The central class for managing and drawing a widget tree.
Definition layout.hh:17
static Style * create(StyleAttrs *attrs)
Definition style.hh:628
static Layout * layout

After this, the attributes of a dw::core::style::Style should not be changed anymore, since styles are often shared between different widgets etc. (see below). Most times, you simply copy the attributes of another style (possible, since dw::core::style::Style is a sub class of dw::core::style::StyleAttrs), modify them and create a new style:

styleAttrs = *anotherStyle;
styleAttrs.foo = baz;
style = dw::core::style::Style::create (&styleAttrs, layout);

The dw::core::style::Font structure can be created by dw::core::style::Font::create, in a similar, with dw::core::style::FontAttrs, and colors by dw::core::style::Color::create, passing 0xrrggbb as an argument. Furthermore, there is dw::core::style::Tooltip, created by dw::core::style::Tooltip::create.

Notice that fonts, colors and tooltips are only intended to be used in conjunction with dw::core::style::Style.

Naming

dw::core::style::Style will become important for CSS, each CSS attribute, which is supported by dillo, will refer to an attribute in dw::core::style::Style. For this reason, the attributes in dw::core::style::Style get the names from the CSS attributes, with "camelCase" instead of hyphens (e.g. "background-color" becomes "backgroundColor").

However, dw::core::style::Style will be extended by some more attributes, which are not defined by CSS. To distinguish them, they get the prefix "x_", e.g. dw::core::style::Style::x_link.

Lengths and Percentages

dw::core::style::Length is a simple data type for lengths and percentages:

  • A length refers to an absolute measurement. It is used to represent the HTML type Pixels; and the CSS type <length>.

    For CSS lengths, there are two units: (i) pixels and absolute units, which have to be converted to pixels (a pixel is, unlike in the CSS specification, treated as absolute unit), and (ii) the relative units "em" and "ex" (see below).

  • A percentage refers to a value relative to another value. It is used for the HTML type Length; (except Pixels;), and the CSS type <percentage>.

  • A relative length can be used in lists of HTML MultiLengths.

Since many values in CSS may be either lengths or percentages, a single type is very useful.

Useful Functions

Creating lengths:

Examine lengths:

Boxes

The CSS Box Model

For borders, margins etc., the box model defined by CSS2 is used. dw::core::style::Style contains some members defining these attributes. A dw::core::Widget must use these values for any calculation of sizes. There are some helper functions (see dw/style.hh). A dw::core::style::Style box looks quite similar to a CSS box:

Background colors

The background color is stored in dw::core::style::Style::backgroundColor, which may be NULL (the background color of the parent widget is shining through).

For toplevel widgets, this color is set as the background color of the views (dw::core::View::setBgColor), for other widgets, a filled rectangle is drawn, covering the content and padding. (This is compliant with CSS2, the background color of the toplevel element covers the whole canvas.)

Drawing

The following methods may be useful:

Notes on Memory Management

Memory management is done by reference counting, dw::core::style::Style::create returns a pointer to dw::core::style::Style with an increased reference counter, so you should care about calling dw::core::style::Style::unref if it is not used anymore. You do not need to care about the reference counters of fonts and styles.

Lengths are int's. Absolute lengths are represented in the following way:

"auto" lengths are represented as dw::core::style::LENGTH_AUTO.

int  widthRef,
int  heightRef,
Style style,
Color bgColor,
bool  inverse,
bool  atTop 
)

Draw the background (content plus padding) of a region in window, according to style.

Used by dw::core::Widget::drawBox and dw::core::Widget::drawWidgetBox.

"area" is the area to be drawn, "x", "y", "width" and "height" define the box itself (padding box). "xRef", "yRef", "widthRef" and "heightRef" define the reference area, which is important for the tiling of background images (for position 0%/0%, a tile is set at xRef/yRef; for position 100%/100%, a tile is set at xRef + widthRef/yRef + widthRef). See calls for more informations; in most cases, these boxes are identical (padding box). All these coordinates are given in canvas coordinates.

"atTop" should be true, only if the area is drawn directly on the canvas, not on top of other areas; this is only true for the toplevel widget itself (not parts of its contents). Toplevel widget background colors are already set as viewport background color, so that drawing again is is not neccessary, but some time can be saved.

Otherwise, the caller should not try to increase the performance by doing some tests before; this is all done in this method.

"bgColor" is passes implicitly. For non-inversed drawing, style->backgroundColor may simply used. However, when drawing is inversed, and style->backgroundColor is undefined (NULL), a background color defined higher in the hierarchy (which is not accessable here) must be used.

(Background images are never drawn inverse.)
