wxComboCtrl Class Reference

+ Inheritance diagram for wxComboCtrl:

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() )
}
// 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))
{
// TODO: Send event as well
}
protected:
int m_value; // current item index
private:
};
wxBEGIN_EVENT_TABLE(wxListViewComboPopup, wxListView)
EVT_MOTION(wxListViewComboPopup::OnMouseMove)
EVT_LEFT_UP(wxListViewComboPopup::OnMouseClick)

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.

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

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
rectPosition to show the popup window at, in screen coordinates.
flagsCombination of any of the following:
wxComboCtrl::ShowAbove Popup is shown above the control instead of below.
wxComboCtrl::CanDeferShow Showing the popup can be deferred to happen sometime after ShowPopup() has finished. In this case, AnimateShow() must return false.
void wxComboCtrl::EnablePopupAnimation ( bool  enable = true)

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

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

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
fromThe first position.
toThe second position.

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->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

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.
