Detailed Description

Picture widget.

Constructor & Destructor Documentation

◆ Picture()

tgui::Picture::Picture ( const Texture texture,
bool  fullyClickable = true 
)

Constructor to create the picture from a texture.

Parameters
textureThe texture to load the picture from
fullyClickableThis affects what happens when clicking on a transparent pixel in the image. Is the click caught by the picture, or does the event pass to the widgets behind it?
Picture picture1("image.png");
Picture picture2({"image.png", {20, 15, 60, 40}}); // Only load the part of the image from (20,15) to (80,55)
sf::Texture texture;
texture.loadFromFile("image.png", {20, 15, 60, 40});
Picture picture3(texture);

Member Function Documentation

◆ clone()

Widget::Ptr tgui::Picture::clone ( ) const
inlineoverrideprotectedvirtual

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

Reimplemented from tgui::ClickableWidget.

◆ copy()

static Picture::Ptr tgui::Picture::copy ( Picture::ConstPtr  picture)
static

Makes a copy of another picture.

Parameters
pictureThe other picture
Returns
The new picture

◆ create()

static Picture::Ptr tgui::Picture::create ( const Texture texture = {},
bool  fullyClickable = true 
)
static

Creates a new picture widget.

Parameters
textureThe texture to load the picture from
fullyClickableThis affects what happens when clicking on a transparent pixel in the image. Is the click caught by the picture, or does the event pass to the widgets behind it?
Returns
The new picture
auto picture1 = Picture::create("image.png");
auto picture2 = Picture::create({"image.png", {20, 15, 60, 40}}); // Load part of the image from (20,15) to (80,55)
sf::Texture texture;
texture.loadFromFile("image.png", {20, 15, 60, 40});
auto picture3 = Picture::create(texture);

◆ draw()

void tgui::Picture::draw ( sf::RenderTarget &  target,
sf::RenderStates  states 
) const
overridevirtual

Draw the widget to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Reimplemented from tgui::ClickableWidget.

◆ getRenderer()

PictureRenderer* tgui::Picture::getRenderer ( )

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.

◆ getSharedRenderer()

PictureRenderer* tgui::Picture::getSharedRenderer ( )

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

◆ getSignal()

Signal& tgui::Picture::getSignal ( std::string  signalName)
overrideprotectedvirtual

Retrieves a signal based on its name.

Parameters
signalNameName of the signal
Returns
Signal that corresponds to the name
Exceptions
Exceptionwhen the name does not match any signal

Reimplemented from tgui::ClickableWidget.

◆ ignoreMouseEvents()

void tgui::Picture::ignoreMouseEvents ( bool  ignore = true)

Sets whether the widget should completely ignore mouse events and let them pass to the widgets behind it.

Parameters
ignoreShould mouse events be ignored by this widget?

By default, mouse events are NOT ignored.

◆ isIgnoringMouseEvents()

bool tgui::Picture::isIgnoringMouseEvents ( ) const

Returns whether the widget is ignoring mouse events and letting them pass to the widgets behind it.

Returns
Are mouse events ignored by this widget?

◆ mouseOnWidget()

bool tgui::Picture::mouseOnWidget ( sf::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?

Reimplemented from tgui::ClickableWidget.

◆ rendererChanged()

void tgui::Picture::rendererChanged ( const std::string &  property)
overrideprotectedvirtual

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

Parameters
propertyLowercase name of the property that was changed

Reimplemented from tgui::Widget.

◆ setSize()

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

Changes the size of the picture.

Parameters
sizeThe new size of the picture

The image will be scaled to fit this size.

Reimplemented from tgui::Widget.
