Detailed Description

A single-line text input field.

Definition at line 29 of file textfield.hpp.

Constructor & Destructor Documentation

◆ TextField() [1/2]

fcn::TextField::TextField ( )

Definition at line 23 of file textfield.cpp.

◆ TextField() [2/2]

fcn::TextField::TextField ( std::string const & text)
explicit

Constructor.

The text field will be automatically resized to fit the text.

Parameters
textThe default text of the text field.

Definition at line 33 of file textfield.cpp.

References fcn::Widget::addKeyListener(), fcn::Widget::addMouseListener(), adjustSizeImpl(), mStringEditor, mText, and fcn::Widget::setFocusable().

◆ ~TextField()

fcn::TextField::~TextField ( )
override

Definition at line 43 of file textfield.cpp.

Member Function Documentation

◆ adjustHeight()

void fcn::TextField::adjustHeight ( )

Adjusts the height of the text field to fit caption.

Definition at line 192 of file textfield.cpp.

References fcn::Widget::getFont(), fcn::Widget::getHeight(), and fcn::Widget::setHeight().

Referenced by adjustSizeImpl().

◆ adjustSize()

void fcn::TextField::adjustSize ( )
overridevirtual

Adjusts the size of the text field to fit the text.

Reimplemented from fcn::Widget.

Definition at line 178 of file textfield.cpp.

References adjustSizeImpl().

◆ adjustSizeImpl()

void fcn::TextField::adjustSizeImpl ( )
protected

Adjusts the size of the button to fit the caption.

The public adjustSize() method serves as a virtual entry point for polymorphism, while this adjustSizeImpl() method contains the concrete implementation of the resizing logic.

See also
adjustSize (virtual entry point for polymorphism)

Definition at line 183 of file textfield.cpp.

References adjustHeight(), fixScroll(), fcn::Widget::getFont(), mText, fcn::Widget::setWidth(), and fcn::Rectangle::width.

Referenced by adjustSize(), resizeToContent(), and TextField().

◆ draw()

void fcn::TextField::draw ( Graphics * graphics)
overridevirtual

Draws the widget.

The call to draw is initiated by the widget's parent. The graphics object is set up so that all drawing is relative to the widget, i.e coordinate (0,0) is the top left corner of the widget. It is not possible to draw outside of a widget's dimension. If a widget has children, the parent's draw function will always be called before the children's draw functions are called.

Note
A widget with children won't draw its children unless the children area given by Widget::getChildrenArea returns a none empty rectangle inside the widgets dimension. The children area is considered relative to the widget's position.
Parameters
graphicsA graphics object to draw with.
See also
getChildrenArea, drawOutline, drawBorder

Implements fcn::Widget.

◆ drawCaret()

void fcn::TextField::drawCaret ( Graphics * graphics,
int x )
protectedvirtual

Draws the caret.

Overloaded this method if you want to change the style of the caret.

Parameters
graphicsthe Graphics object to draw with.
xthe caret's x-position.

◆ fixScroll()

void fcn::TextField::fixScroll ( )
protected

Ensures the caret remains visible by adjusting horizontal scroll.

Called after text input or caret movement to update the scroll position so the caret is within the visible area.

Definition at line 197 of file textfield.cpp.

References fcn::Widget::getFont(), fcn::Widget::getWidth(), fcn::Widget::isFocused(), mText, and mXScroll.

Referenced by adjustSizeImpl(), fcn::PasswordField::keyPressed(), keyPressed(), mousePressed(), and textInput().

◆ getCaretPosition()

unsigned int fcn::TextField::getCaretPosition ( ) const

Gets the caret position.

As there is only one line of text in a text field the position is the caret's x coordinate.

Returns
The caret position.
See also
setCaretPosition

Definition at line 217 of file textfield.cpp.

References mText.

Referenced by fcn::PasswordField::keyPressed(), keyPressed(), and textInput().

◆ getText()

std::string fcn::TextField::getText ( ) const
virtual

Gets the text of the text field.

Returns
The text of the text field.
See also
setText

Reimplemented in fcn::PasswordField.

Definition at line 222 of file textfield.cpp.

References mText.

Referenced by keyPressed().

◆ isEditable()

bool fcn::TextField::isEditable ( ) const

Checks if the text field is editable.

Returns
True it the text field is editable, false otherwise.
See also
setEditable

Definition at line 227 of file textfield.cpp.

References mEditable.

Referenced by draw().

◆ keyPressed()

void fcn::TextField::keyPressed ( KeyEvent & keyEvent)
overridevirtual

Called if a key is pressed when the widget has keyboard focus.

If a key is held down the widget will generate multiple key presses.

Parameters
keyEventDescribes the event.

Reimplemented from fcn::KeyListener.

Definition at line 127 of file textfield.cpp.

References fcn::InputEvent::consume(), fcn::Widget::distributeActionEvent(), fcn::UTF8StringEditor::eraseChar(), fixScroll(), getCaretPosition(), fcn::KeyEvent::getKey(), getText(), mText, fcn::UTF8StringEditor::nextChar(), fcn::UTF8StringEditor::prevChar(), and setCaretPosition().

◆ mouseDragged()

void fcn::TextField::mouseDragged ( MouseEvent & mouseEvent)
overridevirtual

Called when the mouse has moved and the mouse has previously been pressed on the widget.

Parameters
mouseEventDescribes the event.

Reimplemented from fcn::MouseListener.

Definition at line 122 of file textfield.cpp.

References fcn::InputEvent::consume().

◆ mousePressed()

void fcn::TextField::mousePressed ( MouseEvent & mouseEvent)
overridevirtual

Called when a mouse button has been pressed down on the widget area.

Note
A mouse press is NOT equal to a mouse click. Use mouseClicked() for "pressed AND released" (full click) on a widget.
See also
mouseClicked
Parameters
mouseEventDescribes the event.

Reimplemented from fcn::MouseListener.

Definition at line 114 of file textfield.cpp.

◆ resizeToContent()

void fcn::TextField::resizeToContent ( bool recursion = true)
overridevirtual

Resizes the widget's size to fit the content exactly, calls recursively all childs.

The default value true allows callers to use resizeToContent() without argument.

Parameters
recursionIf true, perform the resize operation recursively on children.

Reimplemented from fcn::Widget.

Definition at line 172 of file textfield.cpp.

References adjustSizeImpl().

◆ setCaretPosition()

void fcn::TextField::setCaretPosition ( unsigned int position)

Sets the caret position.

As there is only one line of text in a text field the position is the caret's x coordinate.

Parameters
positionThe caret position.

References mText.

Referenced by keyPressed(), and textInput().

◆ setEditable()

void fcn::TextField::setEditable ( bool editable)

Sets the text field to be editable or not.

A text field is editable by default.

Parameters
editableTrue if the text field should be editable, false otherwise.

Definition at line 232 of file textfield.cpp.

References mEditable.

◆ setText()

void fcn::TextField::setText ( std::string const & text)

References mText.

◆ textInput()

void fcn::TextField::textInput ( TextInputEvent & event)
overridevirtual

Called when text input (IME, dead-key, paste) is received.

Override this to handle text input in your widget. The default implementation does nothing.

Parameters
eventThe text input event containing the UTF-8 text.

Reimplemented from fcn::Widget.

Definition at line 161 of file textfield.cpp.
