Detailed Description

Class used by bindings to implement custom widgets withing these bindings (e.g. a custom C# widget in TGUI.Net)

Member Function Documentation

◆ canGainFocus()

bool tgui::CustomWidgetForBindings::canGainFocus ( ) const
overridevirtual

Returns whether the widget can gain focus.

Returns
Can the widget be focused?

Reimplemented from tgui::Widget.

◆ clone()

Widget::Ptr tgui::CustomWidgetForBindings::clone ( ) const
inlineoverridevirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns
Copy of the widget
Warning
This function should not be used as it won't function correctly because the binding object isn't changed.

Implements tgui::Widget.

◆ create()

static CustomWidgetForBindings::Ptr tgui::CustomWidgetForBindings::create ( )
static

Creates a new widget.

Returns
The new widget

◆ draw()

void tgui::CustomWidgetForBindings::draw ( BackendRenderTargetBase target,
RenderStates  states 
) const
overridevirtual

Draw the widget to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Implements tgui::Widget.

◆ getAbsolutePosition()

Vector2f tgui::CustomWidgetForBindings::getAbsolutePosition ( ) const
overridevirtual

Get the absolute position of the widget instead of the relative position to its parent.

Returns
Absolute position of the widget

Reimplemented from tgui::Widget.

◆ getFullSize()

Vector2f tgui::CustomWidgetForBindings::getFullSize ( ) const
overridevirtual

Returns the entire size that the widget is using.

This function will return a value equal or greater than what getSize returns. If the widget would e.g. have borders around it then this function will return the size, including these borders.

Returns
Full size of the widget

Reimplemented from tgui::Widget.

◆ getWidgetOffset()

Vector2f tgui::CustomWidgetForBindings::getWidgetOffset ( ) const
overridevirtual

Returns the distance between the position where the widget is drawn and where the widget is placed.

The offset is (0,0) for almost all widgets.

Returns
Offset of the widget

Reimplemented from tgui::Widget.

◆ isMouseOnWidget()

bool tgui::CustomWidgetForBindings::isMouseOnWidget ( Vector2f  pos) const
overridevirtual

Returns whether the mouse position (which is relative to the parent widget) lies on top of the widget.

Returns
Is the mouse on top of the widget?

Implements tgui::Widget.

◆ keyPressed()

void tgui::CustomWidgetForBindings::keyPressed ( const Event::KeyEvent event)
overridevirtual

Reimplemented from tgui::Widget.

◆ leftMouseButtonNoLongerDown()

void tgui::CustomWidgetForBindings::leftMouseButtonNoLongerDown ( )

◆ setEnabled()

void tgui::CustomWidgetForBindings::setEnabled ( bool  enabled)
overridevirtual

Enables or disables the widget.

Parameters
enabledIs 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::CustomWidgetForBindings::setFocused ( bool  focused)
overridevirtual

Focus or unfocus the widget.

Parameters
focusedIs 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.

◆ setPosition()

void tgui::CustomWidgetForBindings::setPosition ( const Layout2d position)
overridevirtual

sets the position of the widget

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable widget is (0, 0).

Parameters
positionNew position
See also
move, getPosition

Usage examples:

// Place the widget on an exact position
widget->setPosition({40, 30});
// Place the widget relative to the size of its parent
widget->setPosition({"5%", "10%"});
// Place the widget 50 pixels below another widget and automatically move it when the other widget moves
widget->setPosition({tgui::bindLeft(otherWidget), tgui::bindBottom(otherWidget) + 50});

Reimplemented from tgui::Widget.

◆ setSize()

void tgui::CustomWidgetForBindings::setSize ( const Layout2d size)
overridevirtual

Changes the size of the widget.

Parameters
sizeSize of the widget

Usage examples:

// Give the widget an exact size
widget->setSize({40, 30});
// Give the widget a size relative to the size of its parent
widget->setSize({"20%", "5%"});
// Make the widget 50 pixels higher than some other widget and automatically resize it when the other widget resizes
widget->setSize({200, tgui::bindHeight(otherWidget) + 50});

Reimplemented from tgui::Widget.

◆ setVisible()

void tgui::CustomWidgetForBindings::setVisible ( bool  visible)
overridevirtual

Shows or hides a widget.

Parameters
visibleIs the widget visible?

The widget won't receive events (and thus won't send callbacks) nor will it be drawn when hidden. The widget is visible by default.

Reimplemented from tgui::Widget.

◆ textEntered()

void tgui::CustomWidgetForBindings::textEntered ( char32_t  key)
overridevirtual

Reimplemented from tgui::Widget.

◆ updateTime()

bool tgui::CustomWidgetForBindings::updateTime ( Duration  elapsedTime)
overridevirtual

Reimplemented from tgui::Widget.
