//======================================
|
|
class UPrefControls
|
|
// The control classes themselves are all private. That's the point. They know what
|
|
// they're doing.
|
|
|
|
// So far, the family includes
|
|
// CPrefTextEdit, CPrefCheckbox, CIntPrefRadio, and CBoolPrefRadio. Each of these
|
|
// has a custom constructor template.
|
|
//
|
|
// These can be added to any window (not just the preferences dialog). You add the
|
|
// control to your window in constructor, put in the pref name (eg
|
|
// "browser.foo.bar.mumble") and a number called "mOrdinal".
|
|
//
|
|
// In most cases, no code will be required. The control initializes itself by querying
|
|
// the pref value during FinishCreate(), and updates the associated preference when
|
|
// destroyed. The latter behavior is determined by a static function call that you
|
|
// should make if the user hits a "cancel" button.
|
|
//
|
|
// The meaning of mOrdinal varies with the type of pane. For a checkbox, mOrdinal
|
|
// is xored with the value when converting between the pref and the control value,
|
|
// allowing a checkbox to be worded in the same or the opposite sense to the pref's
|
|
// semantic. For a boolean radio button group, the one with mOrdinal == 0 corresponds
|
|
// to the pref value and updates its corresponding pref, while the other one must have
|
|
// mOrdinal == 1. For an int radio button group, the one whose ordinal matches the
|
|
// value of the pref gets turned on initially and on destruction, only the one that's
|
|
// on updates its corresponding pref to the value of its mOrdinal field.
|
|
//
|
|
// Future directions might include a popup menu control associated with an int
|
|
// value, an RGAColor pref control, etc. Well, the future is here. It's done.
