API reference - Class InputDialog

Notation used in Ruby API documentation

Description: Various methods to open a dialog requesting data entry

This class provides some basic dialogs to enter a single value. Values can be strings floating-point values, integer values or an item from a list. This functionality is provided through the static (class) methods ask_...

Here are some examples:

# get a double value between -10 and 10 (initial value is 0):
v = RBA::InputDialog::ask_double_ex("Dialog Title", "Enter the value here:", 0, -10, 10, 1)
# get an item from a list:
v = RBA::InputDialog::ask_item("Dialog Title", "Select one:", [ "item 1", "item 2", "item 3" ], 1)

All these examples return the "nil" value if "Cancel" is pressed.

If you have enabled the Qt binding, you can use QInputDialog directly.

Description: Open an input dialog requesting an item from a list

title:The title to display for the dialog
label:The label text to display for the dialog
items:The list of items to show in the selection element
selection:The initial selection (index of the element selected initially)
Returns:The string of the item selected if "Ok" was pressed or nil if "Cancel" was pressed

label:The label text to display for the dialog
value:The initial value for the input field

[const] void assign(const InputDialog other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[const] InputDialog dup

Description: Creates a copy of self
