Class API

class RibbonGallery(RibbonControl)

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

Methods

__init__(self, parent, id=wx.ID_ANY, pos=wx.DefaultPosition, size=wx.DefaultSize, agwStyle=0, name='RibbonGallery')

Default class constructor.

Parameters:

• parent – pointer to a parent window, typically a RibbonPanel;

• id – window identifier. If wx.ID_ANY, will automatically create an identifier;

• pos – window position. wx.DefaultPosition indicates that wxPython should generate a default position for the window;

• size – window size. wx.DefaultSize indicates that wxPython should generate a default size for the window. If no suitable size can be found, the window will be sized to 20x20 pixels so that the window is visible but obviously not correctly sized;

• agwStyle – the AGW-specific window style, currently unused;

• name – the window name.

---

Append(self, bitmap, id, clientData=None)

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

Parameters:

• bitmap – the bitmap to display for the item. Note that all items must have equally sized bitmaps;

• id – id number to associate with the item. Not currently used for anything important;

• 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.

---

CalculateMinSize(self)

---

Clear(self)

Remove all items from the gallery.

---

CommonInit(self, agwStyle)

---

DoGetBestSize(self)

Gets the size which best suits the window: for a control, it would be the minimal size which doesn’t truncate the control, for a panel - the same size as it would have after a call to Fit().

Returns:

An instance of wx.Size.

Note

Overridden from wx.Control.

---

DoGetNextLargerSize(self, direction, relative_to)

Implementation of RibbonControl.GetNextLargerSize().

Controls which have non-continuous sizing must override this virtual function rather than RibbonControl.GetNextLargerSize().

---

DoGetNextSmallerSize(self, direction, relative_to)

Implementation of RibbonControl.GetNextSmallerSize().

Controls which have non-continuous sizing must override this virtual function rather than RibbonControl.GetNextSmallerSize().

---

EnsureVisible(self, item)

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

Parameters:

item – an instance of RibbonGalleryItem.

---

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.

---

GetCount(self)

Get the number of items in the gallery.

---

GetDefaultBorder(self)

Returns the default border style for RibbonGallery.

---

GetDownButtonState(self)

Get the state of the scroll down button.

---

GetExtensionButtonState(self)

Get the state of the “extension” button.

---

GetHoveredItem(self)

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

The hovered item is the item underneath the mouse cursor.

---

GetItem(self, n)

Get an item by index.

Parameters:

n – the zero-based item in the gallery, which is an instance of RibbonGalleryItem.

---

GetItemClientData(self, item)

Get the client data associated with a gallery item.

Parameters:

item – an instance of RibbonGalleryItem.

---

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.

---

GetUpButtonState(self)

Get the state of the scroll up button.

---

IsEmpty(self)

Query if the gallery has no items in it.

---

IsHovered(self)

Query is the mouse is currently hovered over the gallery.

Returns:

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

---

IsSizingContinuous(self)

Returns True if this window can take any size (greater than its minimum size), False if it can only take certain sizes.
