UI Operations Global Undo History Manager
Usage:
var OH = window['piro.sakura.ne.jp'].operationHistory;
// window specific history
window['piro.sakura.ne.jp'].operationHistory.addEntry(
OH.addEntry(
'MyAddonFeature',
{ label : 'Change tabbar position',
onUndo : function() { ... },
onRedo : function() { ... } },
window
);
window['piro.sakura.ne.jp'].operationHistory.undo('MyAddonFeature', window);
window['piro.sakura.ne.jp'].operationHistory.redo('MyAddonFeature', window);
OH.undo('MyAddonFeature', window);
OH.redo('MyAddonFeature', window);
// global history (not associated to window)
window['piro.sakura.ne.jp'].operationHistory.addEntry(
OH.addEntry(
'MyAddonFeature',
{ ... }
);
window['piro.sakura.ne.jp'].operationHistory.undo('MyAddonFeature');
OH.undo('MyAddonFeature');
// anonymous, window specific
window['piro.sakura.ne.jp'].operationHistory.addEntry({ ... }, window);
window['piro.sakura.ne.jp'].operationHistory.undo(window);
OH.addEntry({ ... }, window);
OH.undo(window);
// anonymous, global
window['piro.sakura.ne.jp'].operationHistory.addEntry({ ... });
window['piro.sakura.ne.jp'].operationHistory.undo();
OH.addEntry({ ... });
OH.undo();
// When you want to use "window" object in the global history,
// you should use the ID string instead of the "window" object
// to reduce memory leak. For example...
var id = window['piro.sakura.ne.jp'].operationHistory.getWindowId(targetWindow);
window['piro.sakura.ne.jp'].operationHistory.addEntry({
var id = OH.getWindowId(targetWindow);
OH.addEntry({
onUndo : function() {
// "this" in undo/redo functions refers the operationHistory service itself.
var w = window['piro.sakura.ne.jp'].operationHistory.getWindowById(id);
var w = OH.getWindowById(id);
w.MyAddonService.undoSomething();
},
onRedo : ...
});
// enumerate history entries
var history = OH.getHistory('MyAddonFeature', window); // options are same to undo/redo
OH.entries.forEach(function(aEntry, aIndex) {
var item = MyService.appendItem(aEntry.label);
if (aIndex == history.index)
item.setAttribute('checked', true);
});
