Detailed Description

Base class for button widgets.

Member Function Documentation

draw()

void tgui::ButtonBase::draw ( BackendRenderTarget & target, RenderStates states ) const

overridevirtual

Draw the widget to a render target.

Parameters

target	Render target to draw to
states	Current render states

Implements tgui::Widget.

getIgnoreKeyEvents()

bool tgui::ButtonBase::getIgnoreKeyEvents ( ) const

nodiscard

Returns whether the button ignores space and return key presses and only react to mouse clicks.

Returns

Are space and return key press events ignored by this button?

By default, key events are NOT ignored. This means that when the button is focused, pressing the space or return key has the same effect as clicking the button.

Since

TGUI 1.5

getRenderer()

ButtonRenderer * tgui::ButtonBase::getRenderer ( )

nodiscardoverridevirtual

Returns the renderer, which gives access to functions that determine how the widget is displayed.

Returns

Temporary pointer to the renderer

Warning

After calling this function, the widget has its own copy of the renderer and it will no longer be shared.

Reimplemented from tgui::Widget.

getSharedRenderer() [1/2]

const ButtonRenderer * tgui::ButtonBase::getSharedRenderer ( ) const

nodiscardoverridevirtual

Reimplemented from tgui::Widget.

getSharedRenderer() [2/2]

ButtonRenderer * tgui::ButtonBase::getSharedRenderer ( )

nodiscardoverridevirtual

Returns the renderer, which gives access to functions that determine how the widget is displayed.

Returns

Temporary pointer to the renderer that may be shared with other widgets using the same renderer

Reimplemented from tgui::Widget.

getText()

const String & tgui::ButtonBase::getText ( ) const

nodiscard

Returns the caption of the button.

Returns

Text that is drawn on top of the button

isMouseOnWidget()

bool tgui::ButtonBase::isMouseOnWidget ( Vector2f pos ) const

nodiscardoverridevirtual

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.

leftMouseButtonNoLongerDown()

void tgui::ButtonBase::leftMouseButtonNoLongerDown ( )

overridevirtual

Reimplemented from tgui::Widget.

leftMousePressed()

bool tgui::ButtonBase::leftMousePressed ( Vector2f pos )

overridevirtual

Called by the parent when the left mouse button goes down on top of the widget.

Parameters

pos	Mouse position in view coordinates relative to the parent widget

Returns

True if the clicked part of the widget is draggable, i.e. if the widget should continue to receive mouse move events until the mouse is released, even when the mouse leaves the widget. When false is returned, the mouse move events will only be sent to the widget as long as the mouse is on top of the widget.

Reimplemented from tgui::Widget.

leftMouseReleased()

void tgui::ButtonBase::leftMouseReleased ( Vector2f pos )

overridevirtual

Reimplemented from tgui::Widget.

load()

void tgui::ButtonBase::load ( const std::unique_ptr< DataIO::Node > & node, const LoadingRenderersMap & renderers )

overrideprotectedvirtual

Loads the widget from a tree of nodes.

Reimplemented from tgui::Widget.

Reimplemented in tgui::ToggleButton.

mouseEnteredWidget()

void tgui::ButtonBase::mouseEnteredWidget ( )

overrideprotectedvirtual

This function is called when the mouse enters the widget.

Reimplemented from tgui::Widget.

mouseLeftWidget()

void tgui::ButtonBase::mouseLeftWidget ( )

overrideprotectedvirtual

This function is called when the mouse leaves the widget.

Reimplemented from tgui::Widget.

rendererChanged()

void tgui::ButtonBase::rendererChanged ( const String & property )

overrideprotectedvirtual

Function called when one of the properties of the renderer is changed.

Parameters

property

Name of the property that was changed

Reimplemented from tgui::Widget.

save()

std::unique_ptr< DataIO::Node > tgui::ButtonBase::save ( SavingRenderersMap & renderers ) const

nodiscardoverrideprotectedvirtual

Saves the widget as a tree node in order to save it to a file.

Reimplemented from tgui::Widget.

Reimplemented in tgui::ToggleButton.

setEnabled()

void tgui::ButtonBase::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::ButtonBase::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.

setIgnoreKeyEvents()

void tgui::ButtonBase::setIgnoreKeyEvents

(

bool

ignore

)

Sets whether the button should ignore space and return key pressed and only react to mouse clicks.

Parameters

ignore

Should space and return key press events be ignored by this button?

By default, key events are NOT ignored. This means that when the button is focused, pressing the space or return key has the same effect as clicking the button.

Since

TGUI 1.5

setSize() [1/2]

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

overridevirtual

Changes the size of the button.

Parameters

size	The new size of the button

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

setText()

virtual void tgui::ButtonBase::setText ( const String & caption )

virtual

Changes the caption of the button.

Parameters

caption

New text to draw on top of the button

setTextPosition()

void tgui::ButtonBase::setTextPosition	(	Vector2< AbsoluteOrRelativeValue >	position,
		Vector2f	origin )

Changes the position of the caption text.

Parameters

position	Position of the text within the button (position can be both relative or absolute)
origin	Origin that determines which part of the text is placed at the given position

The position consists of x and y components which are either a constant (e.g. 5) or a percentage string (e.g. "5%"). The origin consists of x and y components with values between 0 (left/top) and 1 (right/bottom).

The default text position is centered in the button, i.e. ({"50%", "50%"}, {0.5f, 0.5f})

Example that places the left side of the text at 10% of the button width and places the vertical center of the text at 25px from the top of the button:

button->setTextPosition({"10%", 25}, {0, 0.5f});

updateTextSize()

void tgui::ButtonBase::updateTextSize ( )

overrideprotectedvirtual

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

Reimplemented from tgui::Widget.
