Detailed Description

An activity bar widget that displays toggle buttons on the side of a window.

The ActivityBar is a vertical bar that contains toggle buttons for showing/hiding panels (like a sidebar toggle in IDEs).

Definition at line 27 of file activitybar.hpp.

Constructor & Destructor Documentation

ActivityBar()

fcn::ActivityBar::ActivityBar ( int width = 48 )

explicit

Constructor.

Parameters

width

The width of the activity bar.

Definition at line 14 of file activitybar.cpp.

References fcn::Container::setLayout(), and fcn::Container::setOpaque().

Member Function Documentation

action()

void fcn::ActivityBar::action ( ActionEvent const & actionEvent )

overrideprotectedvirtual

Handles an action event emitted by a widget.

Invoked when a widget triggers an action, providing details about the event via the ActionEvent object.

Parameters

actionEvent

The action event data.

Implements fcn::ActionListener.

Definition at line 107 of file activitybar.cpp.

addActionListener()

void fcn::ActivityBar::addActionListener

(

ActionListener *

listener

)

Adds an action listener to the activity bar.

Parameters

listener

The listener to add.

Definition at line 45 of file activitybar.cpp.

adjustSize()

void fcn::ActivityBar::adjustSize ( )

overridevirtual

Resizes the widget's size to fit the content exactly.

Reimplemented from fcn::Widget.

Definition at line 84 of file activitybar.cpp.

References fcn::Container::adjustSize(), fcn::Widget::getHeight(), and fcn::Widget::setSize().

draw()

void fcn::ActivityBar::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

graphics

A graphics object to draw with.

getChildrenArea, drawOutline, drawBorder

Implements fcn::Widget.

Definition at line 91 of file activitybar.cpp.

References fcn::Container::draw(), fcn::Graphics::drawLine(), fcn::Graphics::fillRectangle(), fcn::Widget::getBackgroundColor(), fcn::Widget::getForegroundColor(), fcn::Widget::getHeight(), getWidth(), fcn::Container::isOpaque(), and fcn::Graphics::setColor().

getSpacing()

unsigned int fcn::ActivityBar::getSpacing

(

)

const

Gets the spacing between items.

Returns

The spacing in pixels.

See also

setSpacing

Definition at line 39 of file activitybar.cpp.

getWidth()

int fcn::ActivityBar::getWidth

(

)

const

Gets the width of the activity bar.

Returns

The width in pixels.

setWidth

Definition at line 28 of file activitybar.cpp.

hideAll()

void fcn::ActivityBar::hideAll

(

)

Hides all panels (toggles all buttons to unselected state).

Definition at line 67 of file activitybar.cpp.

References fcn::Widget::getChildren().

removeActionListener()

void fcn::ActivityBar::removeActionListener

(

ActionListener *

listener

)

Removes an action listener from the activity bar.

Parameters

listener

The listener to remove.

Definition at line 52 of file activitybar.cpp.

resizeToContent()

void fcn::ActivityBar::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

recursion

If true, perform the resize operation recursively on children.

Reimplemented from fcn::Widget.

Definition at line 77 of file activitybar.cpp.

References fcn::Widget::getHeight(), fcn::Container::resizeToContent(), and fcn::Widget::setSize().

setSpacing()

void fcn::ActivityBar::setSpacing

(

unsigned int

spacing

)

Sets the spacing between items.

Parameters

spacing

The spacing in pixels.

See also

getSpacing

Definition at line 33 of file activitybar.cpp.

References fcn::Container::setVerticalSpacing().

setWidth()

void fcn::ActivityBar::setWidth ( int width )

overridevirtual

Sets the width of the activity bar.

Parameters

width

The width in pixels.

See also

getWidth

Reimplemented from fcn::Widget.

Definition at line 20 of file activitybar.cpp.

References fcn::Widget::getHeight(), and fcn::Widget::setSize().

showAll()

void fcn::ActivityBar::showAll

(

)

Shows all panels (toggles all buttons to selected state).
