wx.ComboCtrl¶

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 ComboCtrl¶

wx.ComboCtrl needs to be told somehow which control to use and this is done by SetPopupControl. However, we need something more than just a wx.Control in this method as, for example, we need to call SetStringValue(“initial text value”) and wx.Control doesn’t have such method. So we also need a wx.ComboPopup which is an interface which must be implemented by a control to be usable as a popup. We couldn’t derive wx.ComboPopup from wx.Control 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 wx.ListView popup:

"""
A simple test case for wx.ComboCtrl using a wx.ListCtrl for the popup
"""

import wx

#----------------------------------------------------------------------
# This class is used to provide an interface between a ComboCtrl and the
# ListCtrl that is used as the popup for the combo widget.

class ListCtrlComboPopup(wx.ComboPopup):

    def __init__(self):
        wx.ComboPopup.__init__(self)
        self.lc = None

    def AddItem(self, txt):
        self.lc.InsertItem(self.lc.GetItemCount(), txt)

    def OnMotion(self, evt):
        item, flags = self.lc.HitTest(evt.GetPosition())
        if item >= 0:
            self.lc.Select(item)
            self.curitem = item

    def OnLeftDown(self, evt):
        self.value = self.curitem
        self.Dismiss()


    # The following methods are those that are overridable from the
    # ComboPopup base class.  Most of them are not required, but all
    # are shown here for demonstration purposes.

    # This is called immediately after construction finishes.  You can
    # use self.GetCombo if needed to get to the ComboCtrl instance.
    def Init(self):
        self.value = -1
        self.curitem = -1

    # Create the popup child control.  Return true for success.
    def Create(self, parent):
        self.lc = wx.ListCtrl(parent, style=wx.LC_LIST | wx.LC_SINGLE_SEL | wx.SIMPLE_BORDER)
        self.lc.Bind(wx.EVT_MOTION, self.OnMotion)
        self.lc.Bind(wx.EVT_LEFT_DOWN, self.OnLeftDown)
        return True

    # Return the widget that is to be used for the popup
    def GetControl(self):
        return self.lc

    # Called just prior to displaying the popup, you can use it to
    # 'select' the current item.
    def SetStringValue(self, val):
        idx = self.lc.FindItem(-1, val)
        if idx != wx.NOT_FOUND:
            self.lc.Select(idx)

    # Return a string representation of the current item.
    def GetStringValue(self):
        if self.value >= 0:
            return self.lc.GetItemText(self.value)
        return ""

    # Called immediately after the popup is shown
    def OnPopup(self):
        wx.ComboPopup.OnPopup(self)

    # Called when popup is dismissed
    def OnDismiss(self):
        wx.ComboPopup.OnDismiss(self)

    # This is called to custom paint in the combo control itself
    # (ie. not the popup).  Default implementation draws value as
    # string.
    def PaintComboControl(self, dc, rect):
        wx.ComboPopup.PaintComboControl(self, dc, rect)

    # Receives key events from the parent ComboCtrl.  Events not
    # handled should be skipped, as usual.
    def OnComboKeyEvent(self, event):
        wx.ComboPopup.OnComboKeyEvent(self, event)

    # Implement if you need to support special action when user
    # double-clicks on the parent wxComboCtrl.
    def OnComboDoubleClick(self):
        wx.ComboPopup.OnComboDoubleClick(self)

    # Return final size of popup. Called on every popup, just prior to OnPopup.
    # minWidth = preferred minimum width for window
    # prefHeight = preferred height. Only applies if > 0,
    # maxHeight = max height for window, as limited by screen size
    #   and should only be rounded down, if necessary.
    def GetAdjustedSize(self, minWidth, prefHeight, maxHeight):
        return wx.ComboPopup.GetAdjustedSize(self, minWidth, prefHeight, maxHeight)

    # Return true if you want delay the call to Create until the popup
    # is shown for the first time. It is more efficient, but note that
    # it is often more convenient to have the control created
    # immediately.
    # Default returns false.
    def LazyCreate(self):
        return wx.ComboPopup.LazyCreate(self)

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

comboCtrl = wx.ComboCtrl(self, wx.ID_ANY, "")

popupCtrl = ListViewComboPopup()

# It is important to call SetPopupControl() as soon as possible
comboCtrl.SetPopupControl(popupCtrl)

# Populate using wx.ListView methods
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "First Item")
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "Second Item")
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "Third Item")

Window Styles¶

This class supports the following styles:

wx.CB_READONLY: Text will not be editable.
wx.CB_SORT: Sorts the entries in the list alphabetically.
wx.TE_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.
wx.CC_SPECIAL_DCLICK: Double-clicking triggers a call to popup’s OnComboDoubleClick. Actual behaviour is defined by a derived class. For instance, wx.adv.OwnerDrawnComboBox will cycle an item. This style only applies if wx.CB_READONLY is used as well.
wx.CC_STD_BUTTON: Drop button will behave more like a standard push button.

Events Emitted by this Class¶

Handlers bound for the following event types will receive one of the wx.CommandEvent parameters.

EVT_TEXT: Process a wxEVT_TEXT event, when the text changes.
EVT_TEXT_ENTER: Process a wxEVT_TEXT_ENTER event, when RETURN is pressed in the combo control.
EVT_COMBOBOX_DROPDOWN: Process a wxEVT_COMBOBOX_DROPDOWN event, which is generated when the popup window is shown (drops down).
EVT_COMBOBOX_CLOSEUP: 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.

The parameters are the same as those for DoShowPopup .

Parameters:

rect (wx.Rect)
flags (int)

Return type:

bool

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.

Note

If you have implemented OnButtonClick to do something else than show the popup, then DoSetPopupControl must always set popup to None.

DoShowPopup(self, rect, flags)¶

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).

Return type:: int
Returns:: Value returned is a combination of the flags defined in wx.ComboCtrlFeatures.

GetHint(self)¶

Returns the current hint string.

See SetHint for more information about hints.

Return type:: str

Added in version 2.9.1.

pushButtonBg (bool) – If True, blank push button background is painted below the image.
bmpPressed (wx.BitmapBundle) – Depressed button image.
bmpHover (wx.BitmapBundle) – Button image when mouse hovers above it. This should be ignored on platforms and themes that do not generally draw different kind of button on mouse hover.
bmpDisabled (wx.BitmapBundle) – Disabled button image.

Return type:

None

SetButtonPosition(self, width=-1, height=-1, side=RIGHT, spacingX=0)¶

Sets size and position of dropdown button.

Parameters:

width (int) – Button width. Value = 0 specifies default.
height (int) – Button height. Value = 0 specifies default.
side (int) – Indicates which side the button will be placed. Value can be wx.LEFT or wx.RIGHT.
spacingX (int) – Horizontal spacing around the button. Default is 0.

Return type:

None

SetCustomPaintWidth(self, width)¶

Set width, in pixels, of custom painted area in control without CB_READONLY style.

In read-only wx.adv.OwnerDrawnComboBox, this is used to indicate area that is not covered by the focus rectangle.

Parameters:: width (int)
Return type:: None

SetHint(self, hint)¶

Sets a hint shown in an empty unfocused combo control.

Notice that hints are known as cue banners under MSW or placeholder strings under macOS.

Parameters:: hint (string)
Return type:: bool

Added in version 2.9.1.

See also

wx.TextEntry.SetHint

SetInsertionPoint(self, pos)¶

Sets the insertion point in the text field.

Parameters:: pos (long) – The new insertion point.
Return type:: None

SetInsertionPointEnd(self)¶

Sets the insertion point at the end of the combo control text field.

Return type:: None

SetMainControl(self, win)¶

Uses the given window instead of the default text control as the main window of the combo control.

By default, combo controls without CB_READONLY style create a wx.TextCtrl which shows the current value and allows to edit it. This method allows to use some other window instead of this wx.TextCtrl.

This method can be called after creating the combo fully, however in this case a wx.TextCtrl is unnecessarily created just to be immediately destroyed when it’s replaced by a custom window. If you wish to avoid this, you can use the following approach, also shown in the combo sample:

# Create the combo control using its default ctor.
combo = wx.ComboCtrl()

# Create the custom main control using its default ctor too.
someMainWindow = SomeWindow()

# Set the custom main control before creating the combo.
combo.SetMainControl(someMainWindow)

# And only create it now: wx.TextCtrl won't be unnecessarily
# created because the combo already has a main window.
combo.Create(panel, wx.ID_ANY, "")

# Finally create the main window itself, now that its parent was
# created.
someMainWindow.Create(combo, ...)

Note that when a custom main window is used, none of the methods of this class inherited from wx.TextEntry, such as SetValue , Replace , SetInsertionPoint etc do anything and simply return.

Parameters:: win (wx.Window)
Return type:: None

Added in version 4.1/wxWidgets-3.1.6.

SetMargins(self, *args, **kw)¶

Attempts to set the control margins.

When margins are given as wx.Point, 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.

Added in version 2.9.1.

Overloaded Implementations:

SetMargins (self, pt)

Parameters:: pt (wx.Point)
Return type:: bool

SetMargins (self, left, top=-1)

Parameters:

left (int)
top (int)

Return type:

bool

SetPopupAnchor(self, anchorSide)¶

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

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

Parameters:: anchorSide (int)
Return type:: None

SetPopupControl(self, popup)¶

Set popup interface class derived from wx.ComboPopup.

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

Parameters:: popup (wx.ComboPopup)
Return type:: None

SetPopupExtents(self, extLeft, extRight)¶

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

Parameters:

extLeft (int) – How many pixel to extend beyond the left edge of the control. Default is 0.
extRight (int) – How many pixel to extend beyond the right edge of the control. Default is 0.

Return type:

None

Note

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

SetPopupMaxHeight(self, height)¶

Sets preferred maximum height of the popup.

Parameters:: height (int)
Return type:: None

Note

Value -1 indicates the default.

SetPopupMinWidth(self, width)¶

Sets minimum width of the popup.

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

Parameters:: width (int)
Return type:: None

Note

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

SetSelection(self, frm, to)¶

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

Parameters:

frm (long)
to (long) – The second position.

The first position.

Return type:: None

SetText(self, value)¶

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

Thus, unlike SetValue , it works equally well with combo control using CB_READONLY style.

Parameters:: value (string)
Return type:: None

SetTextCtrlStyle(self, style)¶

Set a custom window style for the embedded wx.TextCtrl.

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

comboCtrl = wx.ComboCtrl()

# Let's make the text right-aligned
comboCtrl.SetTextCtrlStyle(wx.TE_RIGHT)

comboCtrl.Create(parent, wx.ID_ANY, "")

Parameters:: style (int)
Return type:: None

SetValue(self, value)¶

Sets the text for the combo control text field.

Parameters:: value (string)
Return type:: None

Note

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

SetValueByUser(self, value)¶

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

Parameters:: value (string)
Return type:: None

ShouldDrawFocus(self)¶

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

Return type:: bool

ShowPopup(self)¶

Show the popup.

Return type:: None

Deprecated

Use Popup instead.

Undo(self)¶

Undoes the last edit in the text field.

Windows only.

Return type:: None

UseAltPopupWindow(self, 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 wx.Dialog, and as such, when it is shown, its parent top-level window will appear as if the focus has been lost from it.
