""" A ribbon button bar is similar to a traditional toolbar. Description =========== It contains one or more buttons (button bar buttons, not wx.Buttons), each of which has a label and an icon. It differs from a L{RibbonToolBar} in several ways: - Individual buttons can grow and contract. - Buttons have labels as well as bitmaps. - Bitmaps are typically larger (at least 32x32 pixels) on a button bar compared to a tool bar (which typically has 16x15). - There is no grouping of buttons on a button bar - A button bar typically has a border around each individual button, whereas a tool bar typically has a border around each group of buttons. Events Processing ================= This class processes the following events: ======================================== ======================================== Event Name Description ======================================== ======================================== ``EVT_RIBBONBUTTONBAR_CLICKED`` Triggered when the normal (non-dropdown) region of a button on the button bar is clicked. ``EVT_RIBBONBUTTONBAR_DROPDOWN_CLICKED`` Triggered when the dropdown region of a button on the button bar is clicked. L{RibbonButtonBarEvent.PopupMenu} should be called by the event handler if it wants to display a popup menu (which is what most dropdown buttons should be doing). ======================================== ======================================== """ import wx from control import RibbonControl from art import * wxEVT_COMMAND_RIBBONBUTTON_CLICKED = wx.NewEventType() wxEVT_COMMAND_RIBBONBUTTON_DROPDOWN_CLICKED = wx.NewEventType() EVT_RIBBONBUTTONBAR_CLICKED = wx.PyEventBinder(wxEVT_COMMAND_RIBBONBUTTON_CLICKED, 1) EVT_RIBBONBUTTONBAR_DROPDOWN_CLICKED = wx.PyEventBinder(wxEVT_COMMAND_RIBBONBUTTON_DROPDOWN_CLICKED, 1) class RibbonButtonBarButtonSizeInfo(object): def __init__(self): self.is_supported = True self.size = wx.Size() self.normal_region = wx.Rect() self.dropdown_region = wx.Rect() class RibbonButtonBarButtonInstance(object): def __init__(self): self.position = wx.Point() self.base = None self.size = wx.Size() class RibbonButtonBarButtonBase(object): def __init__(self): self.label = "" self.help_string = "" self.bitmap_large = wx.NullBitmap self.bitmap_large_disabled = wx.NullBitmap self.bitmap_small = wx.NullBitmap self.bitmap_small_disabled = wx.NullBitmap self.sizes = [RibbonButtonBarButtonSizeInfo() for i in xrange(3)] self.client_data = None self.id = -1 self.kind = None self.state = None def NewInstance(self): i = RibbonButtonBarButtonInstance() i.base = self return i def GetLargestSize(self): if self.sizes[RIBBON_BUTTONBAR_BUTTON_LARGE].is_supported: return RIBBON_BUTTONBAR_BUTTON_LARGE if self.sizes[RIBBON_BUTTONBAR_BUTTON_MEDIUM].is_supported: return RIBBON_BUTTONBAR_BUTTON_MEDIUM return RIBBON_BUTTONBAR_BUTTON_SMALL def GetSmallerSize(self, size, n=1): for i in xrange(n, 0, -1): if size == RIBBON_BUTTONBAR_BUTTON_LARGE: if self.sizes[RIBBON_BUTTONBAR_BUTTON_MEDIUM].is_supported: return True, RIBBON_BUTTONBAR_BUTTON_MEDIUM elif size == RIBBON_BUTTONBAR_BUTTON_MEDIUM: if self.sizes[RIBBON_BUTTONBAR_BUTTON_SMALL].is_supported: return True, RIBBON_BUTTONBAR_BUTTON_SMALL else: return False, None class RibbonButtonBarLayout(object): def __init__(self): self.overall_size = wx.Size() self.buttons = [] def CalculateOverallSize(self): self.overall_size = wx.Size(0, 0) for instance in self.buttons: size = instance.base.sizes[instance.size].size right = instance.position.x + size.GetWidth() bottom = instance.position.y + size.GetHeight() if right > self.overall_size.GetWidth(): self.overall_size.SetWidth(right) if bottom > self.overall_size.GetHeight(): self.overall_size.SetHeight(bottom) def FindSimilarInstance(self, inst): if inst is None: return None for instance in self.buttons: if instance.base == inst.base: return instance return None class RibbonButtonBarEvent(wx.PyCommandEvent): """ Event used to indicate various actions relating to a button on a L{RibbonButtonBar}.
