Detailed Description

A combo control is a generic combobox that allows totally custom popup.

In addition it has other customization features. For instance, position and size of the dropdown button can be changed.

Setting Custom Popup for wxComboCtrl

wxComboCtrl needs to be told somehow which control to use and this is done by SetPopupControl(). However, we need something more than just a wxControl in this method as, for example, we need to call SetStringValue("initial text value") and wxControl doesn't have such method. So we also need a wxComboPopup which is an interface which must be implemented by a control to be usable as a popup.

We couldn't derive wxComboPopup from wxControl as this would make it impossible to have a class deriving from a wxWidgets control and from it, so instead it is just a mix-in.

Here's a minimal sample of wxListView popup:

#include <wx/combo.h>
#include <wx/listctrl.h>
class wxListViewComboPopup : public wxListView, public wxComboPopup
{
public:
    // Initialize member variables
    virtual void Init()
    {
        m_value = -1;
    }
    // Create popup control
    virtual bool Create(wxWindow* parent)
    {
        return wxListView::Create(parent,1,wxPoint(0,0),wxDefaultSize);
    }
    // Return pointer to the created control
    virtual wxWindow *GetControl() { return this; }
    // Translate string into a list selection
    virtual void SetStringValue(const wxString& s)
    {
        int n = wxListView::FindItem(-1,s);
        if ( n >= 0 && n < wxListView::GetItemCount() )
            wxListView::Select(n);
    }
    // Get list selection as a string
    virtual wxString GetStringValue() const
    {
        if ( m_value >= 0 )
        return wxListView::GetItemText(m_value);
        return wxEmptyString;
    }
    // Do mouse hot-tracking (which is typical in list popups)
    void OnMouseMove(wxMouseEvent& event)
    {
        // TODO: Move selection to cursor
    }
    // On mouse left up, set the value and close the popup
    void OnMouseClick(wxMouseEvent& WXUNUSED(event))
    {
        m_value = wxListView::GetFirstSelected();
        // TODO: Send event as well
        Dismiss();
    }
protected:
    int m_value; // current item index
private:
    wxDECLARE_EVENT_TABLE();
};
wxBEGIN_EVENT_TABLE(wxListViewComboPopup, wxListView)
    EVT_MOTION(wxListViewComboPopup::OnMouseMove)
    EVT_LEFT_UP(wxListViewComboPopup::OnMouseClick)
wxEND_EVENT_TABLE()

Here's how you would create and populate it in a dialog constructor:

wxComboCtrl* comboCtrl = new wxComboCtrl(this, wxID_ANY, wxEmptyString);
wxListViewComboPopup* popupCtrl = new wxListViewComboPopup();
// It is important to call SetPopupControl() as soon as possible
comboCtrl->SetPopupControl(popupCtrl);
// Populate using wxListView methods
popupCtrl->InsertItem(popupCtrl->GetItemCount(), "First Item");
popupCtrl->InsertItem(popupCtrl->GetItemCount(), "Second Item");
popupCtrl->InsertItem(popupCtrl->GetItemCount(), "Third Item");

Styles

This class supports the following styles:

wxCB_READONLY:
Text will not be editable.
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). Windows only.
wxCC_SPECIAL_DCLICK:
Double-clicking triggers a call to popup's OnComboDoubleClick. Actual behaviour is defined by a derived class. For instance, wxOwnerDrawnComboBox will cycle an item. This style only applies if wxCB_READONLY is used as well.
wxCC_STD_BUTTON:
Drop button will behave more like a standard push button.

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_TEXT(id, func):
Process a wxEVT_TEXT event, when the text changes.
EVT_TEXT_ENTER(id, func):
Process a wxEVT_TEXT_ENTER event, when RETURN is pressed in the combo control.
EVT_COMBOBOX_DROPDOWN(id, func):
Process a wxEVT_COMBOBOX_DROPDOWN event, which is generated when the popup window is shown (drops down).
EVT_COMBOBOX_CLOSEUP(id, func):
Process a wxEVT_COMBOBOX_CLOSEUP event, which is generated when the popup window of the combo control disappears (closes up). You should avoid adding or deleting items in this event.

Destructor, destroying the combo control.

Member Function Documentation

virtual bool wxComboCtrl::AnimateShow	(	const wxRect &	rect,
		int	flags
	)

protectedvirtual

This member function is not normally called in application code.

Instead, it can be implemented in a derived class to create a custom popup animation.

The parameters are the same as those for DoShowPopup().

Returns: true if animation finishes before the function returns, false otherwise. In the latter case you need to manually call DoShowPopup() after the animation ends.

virtual void wxComboCtrl::Copy ( )

virtual

Copies the selected text to the clipboard.

Reimplemented from wxTextEntry.

bool wxComboCtrl::Create	(	wxWindow *	parent,
		wxWindowID	id = `wxID_ANY`,
		const wxString &	value = `wxEmptyString`,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `0`,
		const wxValidator &	validator = `wxDefaultValidator`,
		const wxString &	name = `wxComboBoxNameStr`
	)

Creates the combo control for two-step construction.

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

virtual void wxComboCtrl::Cut ( )

virtual

Copies the selected text to the clipboard and removes the selection.

Reimplemented from wxTextEntry.

virtual void wxComboCtrl::Dismiss ( )

virtual

Dismisses the popup window.

Notice that calling this function will generate a wxEVT_COMBOBOX_CLOSEUP event.

Since: 2.9.2

virtual void wxComboCtrl::DoSetPopupControl ( wxComboPopup * popup )

protectedvirtual

This member function is not normally called in application code.

Instead, it can be implemented in a derived class to return default wxComboPopup, in case popup is NULL.

Note: If you have implemented OnButtonClick() to do something else than show the popup, then DoSetPopupControl() must always set popup to NULL.

virtual void wxComboCtrl::DoShowPopup	(	const wxRect &	rect,
		int	flags
	)

protectedvirtual

This member function is not normally called in application code.

Instead, it must be called in a derived class to make sure popup is properly shown after a popup animation has finished (but only if AnimateShow() did not finish the animation within its function scope).

Parameters

rect	Position to show the popup window at, in screen coordinates.
flags	Combination of any of the following: wxComboCtrl::ShowAbove, and wxComboCtrl::CanDeferShow.

void wxComboCtrl::EnablePopupAnimation ( bool enable = true )

Enables or disables popup animation, if any, depending on the value of the argument.

If needed feature is missing, you need to instead use wxGenericComboCtrl, which however may lack a native look and feel (but otherwise sports identical API).

Returns: Value returned is a combination of the flags defined in wxComboCtrlFeatures.

virtual wxString wxComboCtrl::GetHint ( ) const

virtual

Returns the current hint string.

See SetHint() for more information about hints.

Since: 2.9.1

Reimplemented from wxTextEntry.

virtual long wxComboCtrl::GetInsertionPoint ( ) const

virtual

		const wxRect &	rect,
		int	flags
	)		const

virtual

Prepare background of combo control or an item in a dropdown list in a way typical on platform.

This includes painting the focus/disabled background and setting the clipping region.

Unless you plan to paint your own focus indicator, you should always call this in your wxComboPopup::PaintComboControl implementation. In addition, it sets pen and text colour to what looks good and proper against the background.

flags: wxRendererNative flags: wxCONTROL_ISSUBMENU: is drawing a list item instead of combo control wxCONTROL_SELECTED: list item is selected wxCONTROL_DISABLED: control/item is disabled

virtual void wxComboCtrl::Remove	(	long	from,

bool wxComboCtrl::SetMargins ( const wxPoint & pt )

Attempts to set the control margins.

When margins are given as wxPoint, x indicates the left and y the top margin. Use -1 to indicate that an existing value should be used.

Returns: true if setting of all requested margins was successful.

Since: 2.9.1

bool wxComboCtrl::SetMargins	(	wxCoord	left,
		wxCoord	top = `-1`
	)

Attempts to set the control margins.

When margins are given as wxPoint, x indicates the left and y the top margin. Use -1 to indicate that an existing value should be used.

Returns: true if setting of all requested margins was successful.

Since: 2.9.1

void wxComboCtrl::SetPopupAnchor ( int anchorSide )

Set side of the control to which the popup will align itself.

Valid values are wxLEFT, wxRIGHT and 0. The default value 0 means that the most appropriate side is used (which, currently, is always wxLEFT).

void wxComboCtrl::SetPopupControl ( wxComboPopup * popup )

Set popup interface class derived from wxComboPopup.

This method should be called as soon as possible after the control has been created, unless OnButtonClick() has been overridden.

void wxComboCtrl::SetPopupExtents	(	int	extLeft,
		int	extRight
	)

Extends popup size horizontally, relative to the edges of the combo control.

Parameters

extLeft	How many pixel to extend beyond the left edge of the control. Default is 0.

Remarks: Popup minimum width may override arguments. It is up to the popup to fully take this into account.

void wxComboCtrl::SetPopupMaxHeight ( int height )

Sets preferred maximum height of the popup.

Remarks: Value -1 indicates the default.

void wxComboCtrl::SetPopupMinWidth ( int width )

Sets minimum width of the popup.

If wider than combo control, it will extend to the left.

Remarks: Value -1 indicates the default. Also, popup implementation may choose to ignore this.

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

virtual

Selects the text between the two positions, in the combo control text field.

Parameters

from	The first position.
to	The second position.

Reimplemented from wxTextEntry.

void wxComboCtrl::SetText ( const wxString & value )

Sets the text for the text field without affecting the popup.

Thus, unlike SetValue(), it works equally well with combo control using wxCB_READONLY style.

void wxComboCtrl::SetTextCtrlStyle ( int style )

Set a custom window style for the embedded wxTextCtrl.

Usually you will need to use this during two-step creation, just before Create(). For example:

wxComboCtrl* comboCtrl = new wxComboCtrl();
// Let's make the text right-aligned
comboCtrl->SetTextCtrlStyle(wxTE_RIGHT);
comboCtrl->Create(parent, wxID_ANY, wxEmptyString);

void wxComboCtrl::SetTextIndent ( int indent )

This will set the space in pixels between left edge of the control and the text, regardless whether control is read-only or not.

Value -1 can be given to indicate platform default.

Deprecated:: Use SetMargins() instead.

virtual void wxComboCtrl::SetValue ( const wxString & value )

virtual

Sets the text for the combo control text field.

Note: For a combo control with wxCB_READONLY style the string must be accepted by the popup (for instance, exist in the dropdown list), otherwise the call to SetValue() is ignored.

Reimplemented from wxTextEntry.

void wxComboCtrl::SetValueByUser ( const wxString & value )

Changes value of the control as if user had done it by selecting an item from a combo box drop-down list.

bool wxComboCtrl::ShouldDrawFocus ( ) const

Returns true if focus indicator should be drawn in the control.

virtual void wxComboCtrl::ShowPopup ( )

virtual

Show the popup.

Deprecated:: Use Popup() instead.

virtual void wxComboCtrl::Undo ( )

virtual

Undoes the last edit in the text field.

Windows only.

Reimplemented from wxTextEntry.

void wxComboCtrl::UseAltPopupWindow ( bool enable = true )

Enable or disable usage of an alternative popup window, which guarantees ability to focus the popup control, and allows common native controls to function normally.

This alternative popup window is usually a wxDialog, and as such, when it is shown, its parent top-level window will appear as if the focus has been lost from it.
