Detailed Description

Edit box widget.

An edit box is a single line input field. It has options like setting a password character or displaying a default text. If you are looking for something with multiple lines, word-wrap and a scrollbar then check out the TextArea class.

Changes the text alignment.

Parameters

alignment The new text alignment

◆ setCaretPosition()

void tgui::EditBox::setCaretPosition ( std::size_t charactersBeforeCaret )

Sets the blinking caret to after a specific character.

Parameters

charactersBeforeCaret The new position

◆ setDefaultText()

void tgui::EditBox::setDefaultText ( const String & text )

Changes the default text of the editbox. This is the text drawn when the edit box is empty.

This text is not affected by the password character.

Parameters

text	The new default text

◆ setEnabled()

void tgui::EditBox::setEnabled ( bool enabled )

overridevirtual

Enables or disables the widget.

Parameters

enabled Is the widget enabled?

The disabled widget will no longer receive events and thus no longer send callbacks. All widgets are enabled by default.

Reimplemented from tgui::Widget.

◆ setFocused()

void tgui::EditBox::setFocused ( bool focused )

overridevirtual

Focus or unfocus the widget.

Parameters

focused Is the widget focused?

When a widget is focused, the previously focused widget will be unfocused.

Warning: This function only works properly when the widget was already added to its parent (e.g. the Gui).

Reimplemented from tgui::Widget.

◆ setInputValidator()

bool tgui::EditBox::setInputValidator ( const String & regex = U".*" )

Defines how the text input should look like.

Parameters

regex Valid regular expression for std::regex to match on text changes

Returns: True when validator was changed, false when std::regex_error was thrown internally.

When the regex does not match when calling the setText function then the edit box contents will be cleared. When it does not match when the user types a character in the edit box, then the input character is rejected.

Examples:

edit1->setInputValidator(EditBox::Validator::Int);

edit2->setInputValidator("[a-zA-Z][a-zA-Z0-9]*");

tgui::EditBox::Validator::Int

static TGUI_API const char32_t * Int

Accept negative and positive integers.

Definition EditBox.hpp:67

◆ setMaximumCharacters()

void tgui::EditBox::setMaximumCharacters ( unsigned int maxChars )

Changes the character limit.

Parameters

maxChars The new character limit. Set it to 0 to disable the limit

This character limit is disabled by default.

◆ setPasswordCharacter()

void tgui::EditBox::setPasswordCharacter ( char32_t passwordChar )

Sets a password character.

Parameters

passwordChar The new password character. If set to 0 then there is no password character

When the text width is limited then this function might remove the last characters in the text if they no longer fit in the EditBox. You can avoid this by setting TextWidthLimited to false (which is the default).

See also: setTextWidthLimited

◆ setReadOnly()

void tgui::EditBox::setReadOnly ( bool readOnly = true )

Makes the edit box read-only or make it writable again.

Parameters

readOnly Should the edit box be read-only?

When the edit box is read-only, you can no longer delete characters and type text. Selecting text, copying text and even calling the setText function will still work.

◆ setSize() [1/2]

void tgui::EditBox::setSize ( const Layout2d & size )

overridevirtual

Changes the size of the edit box.

Parameters

size	The new size of the edit box

Reimplemented from tgui::Widget.

◆ setSize() [2/2]

void tgui::Widget::setSize	(	Layout	width,
		Layout	height )

inline

Changes the size of the widget.

Parameters

width	Width of the widget
height	Height of the widget

Warning: This setSize overload must never be used from internal TGUI code or by custom widget implementations

◆ setSuffix()

void tgui::EditBox::setSuffix ( const String & suffix )

Places a suffix at the right side of the edit box.

Parameters

suffix Text to show on right side of edit box

Setting a suffix can be useful for inputting numbers where you want to unit to be displayed inside the edit box.

◆ setText()

void tgui::EditBox::setText ( const String & text )

Changes the text of the editbox.

Parameters

text	The new text

The last characters of the text might be removed in the following situations:

You have set a character limit and this text contains too much characters.
You have limited the text width and the text does not fit inside the EditBox.

See also: setMaximumCharacters; setTextWidthLimited

◆ setTextWidthLimited()

void tgui::EditBox::setTextWidthLimited ( bool limitWidth )

Should the text width be limited or should you be able to type even if the edit box is full?

Parameters

limitWidth Should there be a text width limit or not

When set to true, you will no longer be able to add text when the edit box is full. The default value is false.

Since: TGUI 1.3

◆ textEntered()

void tgui::EditBox::textEntered ( char32_t key )

overridevirtual

Reimplemented from tgui::Widget.

◆ updateTextSize()

void tgui::EditBox::updateTextSize ( )

overrideprotectedvirtual

Called when the text size is changed (either by setTextSize or via the renderer)

Reimplemented from tgui::Widget.

◆ updateTime()

bool tgui::EditBox::updateTime ( Duration elapsedTime )

overrideprotectedvirtual

Reimplemented from tgui::Widget.
