Member Function Documentation

◆ click()

bool dw::core::Layout::LinkReceiver::click ( Widget widget,
int  link,
int  img,
int  x,
int  y,
EventButton event 
)
virtual

Called, when the user has clicked on a link.

For mouse interaction, this is equivalent to "press" and "release" on the same link. In this case, event contains the "release" event.

When activating links via keyboard is supported, only a "clicked" signal will be emitted, and event will be NULL.

Reimplemented in DilloHtml::HtmlLinkReceiver.

Definition at line 164 of file layout.cc.

◆ enter()

bool dw::core::Layout::LinkReceiver::enter ( Widget widget,
int  link,
int  img,
int  x,
int  y 
)
virtual

Called, when a link is entered, left, or the position has changed.

When a link is entered, this method is called with the respective arguments. When a link is left, this method is called with all three arguments (link, x, y) set to -1.

When coordinates are supported, a change of the coordinates also causes emitting this signal.

◆ press()

bool dw::core::Layout::LinkReceiver::press ( Widget widget,
int  link,
int  img,
int  x,
int  y,
EventButton event
