Detailed Description

Abstract base class for text items.

All other text classes should inherit from this base class.

The NOTIFY_MODIFIED event is send when the text is modified.

Todo:: Validate whether the NOTIFY_MODIFIED is always fired properly. The current implementation is added for some quick testing so some cases might be forgotten.

Common signal handlers:

connect_signal_pre_key_press

Every key can have several behaviors.

Unmodified No modifier is pressed. Control The control key is pressed. Shift The shift key is pressed. Alt The alt key is pressed.

If modifiers together do something else as the sum of the modifiers it's listed separately eg.

Control Moves 10 steps at the time. Shift Selects the text. Control + Shift Inserts 42 in the text.

There are some predefined actions for results. Unhandled The key/modifier is ignored and also reported unhandled. Ignored The key/modifier is ignored and it's expected the inherited classes do the same. Implementation defined The key/modifier is ignored and it's expected the inherited classes will define some meaning to it. Up arrow key pressed.

The behavior is implementation defined.

◆ set_selection()

void gui2::text_box_base::set_selection	(	std::size_t	start,

	)

Sets or clears the text selection.

Setting the selection range will re-position the cursor depending on the selection direction, specified by the length's sign. Selecting beyond the start or end of the text is safe; the final selection will be limited accordingly.

Note: The range extents are measured in Unicode characters, not bytes. Using byte offsets may produce unexpected results depending on the text contents.

Parameters

start	Start offset, in characters.
length	Selection length, in characters. If zero, the current selection is canceled. If negative, the selection extends towards the start of the text and the cursor will be re-positioned in that direction as well; otherwise the selection and cursor extend towards the end.
