Detailed Description

A lightwight scripting safe HTML control. It has limited CSS support, renders most tables, even when nested. You can provide support for loading external images by implementing the GDocumentEnv::GetImageUri method of the GDocumentEnv interface and passing it into GHtml2::SetEnv. All attempts to open URL's are passed into GDocumentEnv::OnNavigate method of the environment if set. Likewise any content inside active scripting tags, e.g. <? ?> will be striped out of the document and passed to GDocumentEnv::OnDynamicContent, which should return the relevant HTML that the script resolves to. A reasonable default implementation of the GDocumentEnv interface is the GDefaultDocumentEnv object.

You can set the content of the control through the GHtml2::Name method.

Retreive any selected content through GHtml2::GetSelection.

Member Function Documentation

char* Html2::GHtml2::GetClass (  )  [inline]

The class' name. Should be overriden in child classes to return the right class name. Mostly used for debugging, but in the win32 port it is also the default WIN32 class name passed to RegisterClass() in GView::CreateClass().

the Class' name for debugging

Reimplemented from GDocView.

void GHtml2::OnContent ( GDocumentEnv::LoadJob *  Res  )  [virtual]

When the env has loaded a resource it can pass it to the doc control via this method. It MUST be thread safe. Often an environment will call this function directly from it's worker thread.

Reimplemented from GDocView.

References GArray< Type >::Add(), GView::Lock(), GView::PostEvent(), and GView::Unlock().

int GHtml2::OnHitTest ( int  x,
int  y 

Return the type of cursor that should be visible when the mouse is at x,y e.g. LCUR_Normal

Reimplemented from GView.

int GHtml2::OnNotify ( GViewI *  Ctrl,
int  Flags 

Called when a child view or view with it's SetNotify() set to this window changes.

The event by default will bubble up to the GWindow at the top of the window heirarchy visiting each GView on the way. If it reaches a GView that processes it then the event stops propergating up the heirarchy.

Reimplemented from GLayout.

References IDC_VSCROLL, and GView::Invalidate().
