fsleyes_widgets.autotextctrl

This module provides the AutoTextCtrl class, an alternative to the wx.TextCtrl, which has auto-completion capability.

I wrote this class because wx.TextCtrl auto-completion does not work under OSX, and the wx.ComboBox does not give me enough fine-grained control with respect to managing focus.

class fsleyes_widgets.autotextctrl.AutoTextCtrl(parent, style=0, modal=True)

Bases: wx._core.Panel

The AutoTextCtrl class is essentially a wx.TextCtrl which is able to dynamically show a list of options to the user, with a AutoCompletePopup.

Create an AutoTextCtrl. Supported style flags are:

• ATC_CASE_SENSITIVE: restrict the auto-completion options to case sensitive matches.

• ATC_NO_PROPAGATE_ENTER: Cause enter events on the AutoCompletePopup to not be propagated upwards as EVT_ATC_TEXT_ENTER events.

Parameters

• parent – The wx parent object.

• style – Style flags.

• modal – If True (the default), the AutoCompletePopup is shoown modally. This option is primarily for testing purposes.

property textCtrl

Returns a reference to the internal wx.TextCtrl.

property popup

Returns a reference to the AutoCompletePopup or None if it is not currently shown.

AutoComplete(options)

Set the list of options to be shown to the user.

GetValue()

Returns the current value shown on this AutoTextCtrl.

SetValue(value)

Sets the current value shown on this AutoTextCtrl.

Note

Calling this method will result in an wx.EVT_TEXT event being generated - use ChangeValue() if you do not want this to occur.

ChangeValue(value)

Sets the current value shown on this AutoTextCtrl.

GetInsertionPoint()

Returns the cursor location in this AutoTextCtrl.

SetInsertionPoint(idx)

Sets the cursor location in this AutoTextCtrl.

GenEnterEvent()

Programmatically generates an EVT_ATC_TEXT_ENTER event.

SetTakeFocus(takeFocus)

If takeFocus is True, this AutoTextCtrl will give itself focus when its AutoCompletePopup is closed.

fsleyes_widgets.autotextctrl.ATC_CASE_SENSITIVE = 1

Syle flag for use with the AutoTextCtrl class. If set, the auto-completion pattern matching will be case sensitive.

fsleyes_widgets.autotextctrl.ATC_NO_PROPAGATE_ENTER = 2

Syle flag for use with the AutoTextCtrl class. If set, enter events which occur on the AutoCompletePopup list will not be propagated as EVT_ATC_TEXT_ENTER events.

fsleyes_widgets.autotextctrl.EVT_ATC_TEXT_ENTER = <wx.core.PyEventBinder object>
