Detailed Description

Implement this interface to handle view events.

All size and position values are in density independent pixels (DIP) unless otherwise indicated. The methods of this class will be called on the browser process UI thread unless otherwise indicated.

Member Function Documentation

GetHeightForWidth()

virtual int CefViewDelegate::GetHeightForWidth ( CefRefPtr< CefView >  view, int  width  )

inlinevirtual

Return the height necessary to display |view| with the provided |width|.

If not specified the result of GetPreferredSize().height will be used by default. Override if |view|'s preferred height depends upon the width (for example, with Labels).

GetMaximumSize()

virtual CefSize CefViewDelegate::GetMaximumSize ( CefRefPtr< CefView >  view )

inlinevirtual

Return the maximum size for |view|.

GetMinimumSize()

virtual CefSize CefViewDelegate::GetMinimumSize ( CefRefPtr< CefView >  view )

inlinevirtual

Return the minimum size for |view|.

GetPreferredSize()

virtual CefSize CefViewDelegate::GetPreferredSize ( CefRefPtr< CefView >  view )

inlinevirtual

Return the preferred size for |view|.

The Layout will use this information to determine the display size.

OnBlur()

virtual void CefViewDelegate::OnBlur ( CefRefPtr< CefView >  view )

inlinevirtual

Called when |view| loses focus.

OnChildViewChanged()

virtual void CefViewDelegate::OnChildViewChanged ( CefRefPtr< CefView >  view, bool  added, CefRefPtr< CefView >  child  )

inlinevirtual

Called when a child of |view| has changed.

If |child| is being added to |view| then |added| will be true. If |child| is being removed from |view| then |added| will be false. If |child| is being reparented the remove notification will be sent to the old parent before the add notification is sent to the new parent. Do not modify the view hierarchy in this callback.

OnFocus()

virtual void CefViewDelegate::OnFocus ( CefRefPtr< CefView >  view )

inlinevirtual

Called when |view| gains focus.

OnLayoutChanged()

virtual void CefViewDelegate::OnLayoutChanged ( CefRefPtr< CefView >  view, const CefRect &  new_bounds  )

inlinevirtual

Called when the layout of |view| has changed.

OnParentViewChanged()

virtual void CefViewDelegate::OnParentViewChanged ( CefRefPtr< CefView >  view, bool  added, CefRefPtr< CefView >  parent  )

inlinevirtual

Called when the parent of |view| has changed.

If |view| is being added to |parent| then |added| will be true. If |view| is being removed from |parent| then |added| will be false. If |view| is being reparented the remove notification will be sent before the add notification. Do not modify the view hierarchy in this callback.

OnThemeChanged()

virtual void CefViewDelegate::OnThemeChanged ( CefRefPtr< CefView >  view )

inlinevirtual

Called when the theme for |view| has changed, after the new theme colors have already been applied.

Views are notified via the component hierarchy in depth-first reverse order (children before parents).

This will be called in the following cases:

1. When |view|, or a parent of |view|, is added to a Window.
2. When the native/OS or Chrome theme changes for the Window that contains |view|. See CefWindowDelegate::OnThemeColorsChanged documentation.
3. When the client explicitly calls CefWindow::ThemeChanged on the Window that contains |view|.

Optionally use this callback to override the new per-View theme colors by calling CefView::SetBackgroundColor or the appropriate component-specific method. See CefWindow::SetThemeColor documentation for how to customize additional Window theme colors.

OnWindowChanged()

virtual void CefViewDelegate::OnWindowChanged ( CefRefPtr< CefView >  view, bool  added  )

inlinevirtual

Called when |view| is added or removed from the CefWindow.
