Detailed Description

A combobox is like a combination of an edit control and a listbox.

It can be displayed as static list with editable or read-only text field; or a drop-down list with text field; or a drop-down list without a text field depending on the platform and presence of wxCB_READONLY style.

A combobox permits a single selection only. Combobox items are numbered from zero.

If you need a customized combobox, have a look at wxComboCtrl, wxOwnerDrawnComboBox, wxComboPopup and the ready-to-use wxBitmapComboBox.

Please refer to wxTextEntry documentation for the description of methods operating with the text entry part of the combobox and to wxItemContainer for the methods operating with the list of strings. Notice that at least under MSW wxComboBox doesn't behave correctly if it contains strings differing in case only so portable programs should avoid adding such strings to this control.

Styles

This class supports the following styles:

• wxCB_SIMPLE:
  Creates a combobox with a permanently displayed list. Windows only.
• wxCB_DROPDOWN:
  Creates a combobox with a drop-down list. MSW and Motif only.
• wxCB_READONLY:
  A combobox with this style behaves like a wxChoice (and may look in the same way as well, although this is platform-dependent), i.e. it allows the user to choose from the list of options but doesn't allow to enter a value not present in the list.
• wxCB_SORT:
  Sorts the entries in the list alphabetically.
• wxTE_PROCESS_ENTER:
  The control will generate the event wxEVT_TEXT_ENTER (otherwise pressing Enter key is either processed internally by the control or used for navigation between dialog controls).

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxCommandEvent& event)

Event macros for events emitted by this class:

• EVT_COMBOBOX(id, func):
  Process a wxEVT_COMBOBOX event, when an item on the list is selected. Note that calling GetValue() returns the new value of selection.
• EVT_TEXT(id, func):
  Process a wxEVT_TEXT event, when the combobox text changes.
• EVT_TEXT_ENTER(id, func):
  Process a wxEVT_TEXT_ENTER event, when RETURN is pressed in the combobox (notice that the combobox must have been created with wxTE_PROCESS_ENTER style to receive this event).
• EVT_COMBOBOX_DROPDOWN(id, func):
  Process a wxEVT_COMBOBOX_DROPDOWN event, which is generated when the list box part of the combo box is shown (drops down). Notice that this event is only supported by wxMSW, wxGTK with GTK+ 2.10 or later, and wxOSX/Cocoa.
• EVT_COMBOBOX_CLOSEUP(id, func):
  Process a wxEVT_COMBOBOX_CLOSEUP event, which is generated when the list box of the combo box disappears (closes up). This event is only generated for the same platforms as wxEVT_COMBOBOX_DROPDOWN above. Also note that only wxMSW and wxOSX/Cocoa support adding or deleting items in this event.

Derived classes should call or replace this function. See wxComboBox() for further details.

virtual void wxComboBox::Dismiss ( )

virtual

Hides the list box portion of the combo box.

Currently this method is implemented in wxMSW, wxGTK and wxOSX/Cocoa.

Notice that calling this function will generate a wxEVT_COMBOBOX_CLOSEUP event except under wxOSX where generation of this event is not supported at all.

Since

2.9.1

virtual int wxComboBox::FindString ( const wxString &  string, bool  caseSensitive = false  ) const

virtual

Finds an item whose label matches the given string.

Parameters

string	String to find.
caseSensitive	Whether search is case sensitive (default is not).

Returns

The zero-based position of the item, or wxNOT_FOUND if the string was not found.

Reimplemented from wxItemContainerImmutable.

virtual unsigned int wxComboBox::GetCount ( ) const

virtual

Returns the number of items in the control.

See Also

IsEmpty()

Implements wxItemContainerImmutable.

virtual int wxComboBox::GetCurrentSelection ( ) const

virtual

Returns the item being selected right now.

This function does the same things as wxChoice::GetCurrentSelection() and returns the item currently selected in the dropdown list if it's open or the same thing as wxControlWithItems::GetSelection() otherwise.

virtual long wxComboBox::GetInsertionPoint ( ) const

virtual

Same as wxTextEntry::GetInsertionPoint().

Note

Under wxMSW, this function always returns 0 if the combobox doesn't have the focus.

Reimplemented from wxTextEntry.

virtual int wxComboBox::GetSelection ( ) const

virtual

Returns the index of the selected item or wxNOT_FOUND if no item is selected.

Returns

The position of the current selection.

Remarks

This method can be used with single selection list boxes only, you should use wxListBox::GetSelections() for the list boxes with wxLB_MULTIPLE style.

See Also

SetSelection(), GetStringSelection()

Implements wxItemContainerImmutable.

virtual void wxComboBox::GetSelection ( long *  from, long *  to  ) const

virtual

Gets the current selection span.

If the returned values are equal, there was no selection. Please note that the indices returned may be used with the other wxTextCtrl methods but don't necessarily represent the correct indices into the string returned by GetValue() for multiline controls under Windows (at least,) you should use GetStringSelection() to get the selected text.

Parameters

from	The returned first position.
to	The returned last position.

wxPerl Note: In wxPerl this method takes no parameters and returns a 2-element list (from, to).

Reimplemented from wxTextEntry.

virtual wxString wxComboBox::GetString ( unsigned int  n ) const

virtual

Returns the label of the item with the given index.

Parameters

n	The zero-based index.

Returns

The label of the item or an empty string if the position was invalid.

Implements wxItemContainerImmutable.

virtual wxString wxComboBox::GetStringSelection ( ) const

virtual

Gets the text currently selected in the control.

If there is no selection, the returned string is empty.

Reimplemented from wxTextEntry.

bool wxComboBox::IsEmpty ( ) const

virtual

IsEmpty() is not available in this class.

This method is documented here only to notice that it can't be used with this class because of the ambiguity between the methods with the same name inherited from wxItemContainer and wxTextEntry base classes.

Because of this, any attempt to call it results in a compilation error and you should use either IsListEmpty() or IsTextEmpty() depending on what exactly do you want to test.

Reimplemented from wxTextEntry.

bool wxComboBox::IsListEmpty

(

)

const

Returns true if the list of combobox choices is empty.

Use this method instead of (not available in this class) IsEmpty() to test if the list of items is empty.

Since

2.9.3

bool wxComboBox::IsTextEmpty

(

)

const

Returns true if the text of the combobox is empty.

Use this method instead of (not available in this class) IsEmpty() to test if the text currently entered into the combobox is empty.

Since

2.9.3

virtual void wxComboBox::Popup ( )

virtual

Shows the list box portion of the combo box.

Currently this method is implemented in wxMSW, wxGTK and wxOSX/Cocoa.

Notice that calling this function will generate a wxEVT_COMBOBOX_DROPDOWN event except under wxOSX where generation of this event is not supported at all.

Since

2.9.1

virtual void wxComboBox::SetSelection ( long  from, long  to  )

virtual

Same as wxTextEntry::SetSelection().

Reimplemented from wxTextEntry.

virtual void wxComboBox::SetSelection ( int  n )

virtual

Sets the selection to the given item n or removes the selection entirely if n == wxNOT_FOUND.

Note that this does not cause any command events to be emitted nor does it deselect any other items in the controls which support multiple selections.

Parameters

n	The string position to select, starting from zero.

See Also

SetString(), SetStringSelection()

Implements wxItemContainerImmutable.

virtual void wxComboBox::SetString ( unsigned int  n, const wxString &  text  )

virtual

Changes the text of the specified combobox item.

Notice that if the item is the currently selected one, i.e. if its text is displayed in the text part of the combobox, then the text is also replaced with the new text.

Implements wxItemContainerImmutable.

virtual void wxComboBox::SetValue ( const wxString &  text )

virtual

Sets the text for the combobox text field.

Notice that this method will generate a wxEVT_TEXT event, use wxTextEntry::ChangeValue() if this is undesirable.

Note

For a combobox with wxCB_READONLY style the string must be in the combobox choices list, otherwise the call to SetValue() is ignored. This is case insensitive.

Parameters

text	The text to set.

Reimplemented from wxTextEntry.
