Member Function Documentation

bool modm::gui::Widget::checkIntersection ( Widget *  w)
inherited

Check if given Widget w overlaps on top. For widgets overlapping below this function also returns false.

void modm::gui::Widget::draw ( View *  view)
inheritedinline

Interface for drawing widgets. Basically calls render(), but has some logic that needs to be executed before and after rendering a widget

bool modm::gui::WidgetGroup::handleInputEvent ( const InputEvent *  ev)
virtual

Handles InputEvents and calls activate/deactivate if event coordinates are within widgets dimensions. Returning true means, that the event was inside these dimensions, false if not.

Reimplemented from modm::gui::Widget.

void modm::gui::WidgetGroup::setPosition ( const modm::glcd::Point &  pos)
virtual

Set position of widget relative to its parent. Also updates the absolute position by looping through parents.

Reimplemented from modm::gui::Widget.

void modm::gui::Widget::updateIntersections ( WidgetContainer *  widgets)
inherited

Clear old list of intersecting widgets and rebuild on the basis of the given widgets container.

void modm::gui::WidgetGroup::updatePosition ( )
inlinevirtual

Updates the absolute position by looping through all parents and adding up their relative positions.

Reimplemented from modm::gui::Widget.
