// This class allows us to exercise control over the window's title bar. This

|

// area into the title bar. It works like this:
|
|
// 1) We set the window's style to textured.
|
|
// 2) Because of this, the background color applies to the entire window, including
|
|
// the titlebar area. For normal textured windows, the default pattern is a
|
|
// "brushed metal" image on Tiger and a unified gradient on Leopard.
|
|
// 3) We set the background color to a custom NSColor subclass that knows how tall the window is.
|
|
// When -set is called on it, it sets a pattern (with a draw callback) as the fill. In that callback,
|
|
// it paints the the titlebar and background colors in the correct areas of the context it's given,
|
|
// which will fill the entire window (CG will tile it horizontally for us).
|
|
// 4) Whenever the window's main state changes and when [window display] is called,
|
|
// Cocoa redraws the titlebar using the patternDraw callback function.
|
|
//
|
|
// This class also provides us with a pill button to show/hide the toolbar up to 10.6.
|
|
//
|
|
// Drawing the unified gradient in the titlebar and the toolbar works like this:
|
|
// 1) In the style sheet we set the toolbar's -moz-appearance to toolbar or
|
|
// -moz-mac-unified-toolbar.
|
|
// 2) When the toolbar is visible and we paint the application chrome
|
|
// window, the array that Gecko passes nsChildView::UpdateThemeGeometries
|
|
// will contain an entry for the widget type NS_THEME_TOOLBAR or
|
|
// NS_THEME_MOZ_MAC_UNIFIED_TOOLBAR.
|
|
// 3) nsChildView::UpdateThemeGeometries finds the toolbar frame's ToolbarWindow
|
|
// and passes the toolbar frame's height to setUnifiedToolbarHeight.
|
|
// 4) If the toolbar height has changed, a titlebar redraw is triggered and the
|
|
// upper part of the unified gradient is drawn in the titlebar.
|
|
// 5) The lower part of the unified gradient in the toolbar is drawn during
|
|
// normal window content painting in nsNativeThemeCocoa::DrawUnifiedToolbar.
|
|
//
|
|
// Whenever the unified gradient is drawn in the titlebar or the toolbar, both
|
|
// titlebar height and toolbar height must be known in order to construct the
|
|
// correct gradient. But you can only get from the toolbar frame
|
|
// to the containing window - the other direction doesn't work. That's why the
|
|
// toolbar height is cached in the ToolbarWindow but nsNativeThemeCocoa can simply
|
|
// query the window for its titlebar height when drawing the toolbar.
|
|
//
|
|
// Note that in drawsContentsIntoWindowFrame mode, titlebar drawing works in a
|
|
// completely different way: In that mode, the window's mainChildView will
|
|
// cover the titlebar completely and nothing that happens in the window
|
|
// background will reach the screen.
