wx.ribbon.RibbonGallery¶

A ribbon gallery is like a wx.ListBox, but for bitmaps rather than strings.

It displays a collection of bitmaps arranged in a grid and allows the user to choose one. As there are typically more bitmaps in a gallery than can be displayed in the space used for a ribbon, a gallery always has scroll buttons to allow the user to navigate through the entire gallery. It also has an “extension” button, the behaviour of which is outside the scope of the gallery control itself, though it typically displays some kind of dialog related to the gallery.

Events Emitted by this Class¶

Handlers bound for the following event types will receive a wx.ribbon.RibbonGalleryEvent parameter.

EVT_RIBBONGALLERY_SELECTED: Triggered when the user selects an item from the gallery. Note that the ID is that of the gallery, not of the item.
EVT_RIBBONGALLERY_CLICKED: Similar to EVT_RIBBONGALLERY_SELECTED but triggered every time a gallery item is clicked, even if it is already selected. Note that the ID of the event is that of the gallery, not of the item, just as above. This event is available since wxWidgets 2.9.2.
EVT_RIBBONGALLERY_HOVER_CHANGED: Triggered when the item being hovered over by the user changes. The item in the event will be the new item being hovered, or None if there is no longer an item being hovered. Note that the ID is that of the gallery, not of the item.

The following event handler macros redirect the events to member function handlers ‘func’ with prototypes like: wx.CommandEvent

EVT_BUTTON: Triggered when the “extension” button of the gallery is pressed.

Class API¶

class wx.ribbon.RibbonGallery(RibbonControl)¶

Possible constructors:

RibbonGallery() -> None

RibbonGallery(parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize,
              style=0) -> None

A ribbon gallery is like a ListBox, but for bitmaps rather than strings.

Methods¶

__init__(self, *args, **kw)¶

Overloaded Implementations:

__init__ (self)

Default constructor.

With this constructor, Create should be called in order to create the gallery.

Return type:: None

__init__ (self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0)

Construct a ribbon gallery with the given parameters.

Parameters:

parent (wx.Window) – Parent window for the gallery (typically a wx.ribbon.RibbonPanel).
id (wx.WindowID) – An identifier for the gallery. ID_ANY is taken to mean a default.
pos (wx.Point) – Initial position of the gallery.
size (wx.Size) – Initial size of the gallery.
style (long) – Gallery style, currently unused.

Return type:

None

Append(self, *args, **kw)¶

Overloaded Implementations:

Append (self, bitmap, id)

Add an item to the gallery (with no client data).

Parameters:

bitmap (wx.Bitmap) – The bitmap to display for the item. Note that all items must have equally sized bitmaps.
id (int) – ID number to associate with the item. Not currently used for anything important.

Return type:

RibbonGalleryItem

Append (self, bitmap, id, clientData)

Add an item to the gallery (with complex client data)

Parameters:

bitmap (wx.Bitmap) – The bitmap to display for the item. Note that all items must have equally sized bitmaps.
id (int) – ID number to associate with the item. Not currently used for anything important.
clientData (ClientData) – An object which contains data to associate with the item. The item takes ownership of this pointer, and will delete it when the item client data is changed to something else, or when the item is destroyed.

Return type:

RibbonGalleryItem

Clear(self)¶

Remove all items from the gallery.

Return type:: None

Create(self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0)¶

Create a gallery in two-step gallery construction.

Should only be called when the default constructor is used, and arguments have the same meaning as in the full constructor.

Parameters:

parent (wx.Window)
id (wx.WindowID)
pos (wx.Point)
size (wx.Size)
style (long)

Return type:

bool

EnsureVisible(self, item)¶

Scroll the gallery to ensure that the given item is visible.

Parameters:: item (RibbonGalleryItem)
Return type:: None

GetActiveItem(self)¶

Get the currently active item, or None if there is none.

The active item is the item being pressed by the user, and will thus become the selected item if the user releases the mouse button.

Return type:: RibbonGalleryItem

static GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)¶

Parameters:: variant (WindowVariant)
Return type:: VisualAttributes

GetCount(self)¶

Get the number of items in the gallery.

Return type:: int

GetDownButtonState(self)¶

Get the state of the scroll down button.

Return type:: wx.ribbon.RibbonGalleryButtonState

GetExtensionButtonState(self)¶

Get the state of the “extension” button.

Return type:: wx.ribbon.RibbonGalleryButtonState

GetHoveredItem(self)¶

Get the currently hovered item, or None if there is none.

The hovered item is the item underneath the mouse cursor.

Return type:: RibbonGalleryItem

GetItem(self, n)¶

Get an item by index.

Parameters:: n (int)
Return type:: RibbonGalleryItem

GetItemClientData(self, item)¶

Get the client object associated with a gallery item.

Parameters:: item (RibbonGalleryItem)
Return type:: ClientData

GetSelection(self)¶

Get the currently selected item, or None if there is none.

The selected item is set by SetSelection , or by the user clicking on an item.

Return type:: RibbonGalleryItem

GetUpButtonState(self)¶

Get the state of the scroll up button.

Return type:: wx.ribbon.RibbonGalleryButtonState

IsEmpty(self)¶

Query if the gallery has no items in it.

Return type:: bool

IsHovered(self)¶

Query is the mouse is currently hovered over the gallery.

Return type:: bool
Returns:: True if the cursor is within the bounds of the gallery (not just hovering over an item), False otherwise.

ScrollLines(self, lines)¶

Scroll the gallery contents by some amount.

Parameters:: lines (int) – Positive values scroll toward the end of the gallery, while negative values scroll toward the start.
Return type:: bool
Returns:: True if the gallery scrolled at least one pixel in the given direction, False if it did not scroll.

ScrollPixels(self, pixels)¶

Scroll the gallery contents by some fine-grained amount.

Parameters:: pixels (int) – Positive values scroll toward the end of the gallery, while negative values scroll toward the start.
Return type:: bool
Returns:: True if the gallery scrolled at least one pixel in the given direction, False if it did not scroll.
