Overview
A choice item is used to select one of a list of strings.
Unlike a ListBox, only the selection is visible until the user pulls down the menu of choices.
Styles
This class supports the following styles:
-
CB_SORT: Sorts the entries alphabetically.
Events emitted by this class
The following event-handler methods redirect the events to member method or handler blocks for CommandEvent events. Event handler methods for events emitted by this class:
-
EvtHandler#evt_choice(id, meth = nil, &block): Process a EVT_CHOICE event, when an item on the list is selected.
Category: Controls <div class=‘appearance’><span class=‘appearance’>Appearance:</span><table><tr><td> WXMSW Appearance </td><td> WXGTK Appearance </td><td> WXOSX Appearance </td></tr></table></div>

-
#find_string(string, caseSensitive = false) ⇒ Integer
Finds an item whose label matches the given string.
-
#get_columns ⇒ Integer
(also: #columns)
Gets the number of columns in this choice item.
-
#get_count ⇒ Integer
(also: #count)

-
#initialize(*args) ⇒ Choice
constructor
A new instance of Choice.
-
#set_columns(n = 1) ⇒ void
(also: #columns=)
Sets the number of columns in this choice item.
-
#set_selection(n) ⇒ void
(also: #selection=)
Sets the selection to the given item n or removes the selection entirely if n == NOT_FOUND.

Constructor Details
#initialize ⇒ Wx::Choice #initialize(parent, id, pos, size, choices, style = 0, validator = Wx::DEFAULT_VALIDATOR, name = Wx::CHOICE_NAME_STR) ⇒ Wx::Choice
Returns a new instance of Choice.
73 |
# File 'lib/wx/doc/gen/choice.rb', line 73 def initialize(*args) end |
Instance Method Details
#create(parent, id, pos, size, choices, style = 0, validator = Wx::DEFAULT_VALIDATOR, name = Wx::CHOICE_NAME_STR) ⇒ Boolean
Creates the choice for two-step construction.
See choice.
49 |
# File 'lib/wx/doc/gen/choice.rb', line 49 def create(parent, id, pos, size, choices, style=0, validator=Wx::DEFAULT_VALIDATOR, name=Wx::CHOICE_NAME_STR) end |
#find_string(string, caseSensitive = false) ⇒ Integer
Finds an item whose label matches the given string.
The zero-based position of the item, or NOT_FOUND if the string was not found.
138 |
# File 'lib/wx/doc/gen/choice.rb', line 138 def find_string(string, caseSensitive=false) end |
#get_columns ⇒ Integer Also known as: columns
Gets the number of columns in this choice item.
This is implemented for GTK and Motif only and always returns 1 for the other platforms.
83 |
# File 'lib/wx/doc/gen/choice.rb', line 83 def get_columns; end |
#get_count ⇒ Integer Also known as: count
Returns the number of items in the control.
110 |
# File 'lib/wx/doc/gen/choice.rb', line 110 def get_count; end |
#get_current_selection ⇒ Integer Also known as: current_selection
Unlike Wx::ControlWithItems#get_selection which only returns the accepted selection value (the selection in the control once the user closes the dropdown list), this function returns the current selection.
That is, while the dropdown list is shown, it returns the currently selected item in it. When it is not shown, its result is the same as for the other function.
90 |
# File 'lib/wx/doc/gen/choice.rb', line 90 def get_current_selection; end |
#get_selection ⇒ Integer Also known as: selection
Returns the index of the selected item or NOT_FOUND if no item is selected.
The position of the current selection.
119 |
# File 'lib/wx/doc/gen/choice.rb', line 119 def get_selection; end |
#get_string(n) ⇒ String Also known as: string
Returns the label of the item with the given index.
The index must be valid, i.e. less than the value returned by #get_count, otherwise an assert is triggered. Notably, this function can’t be called if the control is empty.
The label of the item.
147 |
# File 'lib/wx/doc/gen/choice.rb', line 147 def get_string(n) end |
#set_columns(n = 1) ⇒ void Also known as: columns=
This method returns an undefined value.
Sets the number of columns in this choice item.
This is implemented for GTK and Motif only and doesn’t do anything under other platforms.
102 |
# File 'lib/wx/doc/gen/choice.rb', line 102 def set_columns(n=1) end |
#set_selection(n) ⇒ void Also known as: selection=
This method returns an undefined value.
Sets the selection to the given item n or removes the selection entirely if n == NOT_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.
129 |
# File 'lib/wx/doc/gen/choice.rb', line 129 def set_selection(n) end |
#set_string(n, string) ⇒ void
This method returns an undefined value.
Sets the label for the given item.
154 |
# File 'lib/wx/doc/gen/choice.rb', line 154 def set_string(n, string) end |
