HTML_PAINTER enumeration

Specifies a behavior's rendering attributes and requirements. Used in the lFlags member of the HTML_PAINTER_INFO structure, which MSHTML retrieves when it calls IHTMLPainter::GetPainterInfo.

Constants

HTMLPAINTER_OPAQUE

The behavior's rendering will be opaque; the behavior will change all pixels in its update rectangle or region and MSHTML does not need to render anything below it.

HTMLPAINTER_TRANSPARENT

The behavior's rendering will be transparent; the behavior might not change all the pixels in its update rectangle or region and MSHTML needs to render content below it.

HTMLPAINTER_ALPHA

Not implemented.

HTMLPAINTER_COMPLEX

Not implemented.

HTMLPAINTER_OVERLAY

The behavior uses DirectDraw hardware overlay planes.

HTMLPAINTER_HITTEST

The behavior supports hit testing; MSHTML will call the IHTMLPainter::HitTestPoint method when relevant events fire on the element to which the behavior is attached.

HTMLPAINTER_SURFACE

The behavior requires a DirectDraw surface.

HTMLPAINTER_3DSURFACE

The behavior requires a Direct3D surface.

HTMLPAINTER_NOBAND

Not implemented.

HTMLPAINTER_NODC

No device context is required.

HTMLPAINTER_NOPHYSICALCLIP

The behavior will draw entirely within its bounding area; MSHTML does not have to apply clipping.

HTMLPAINTER_NOSAVEDC

The behavior will return the device context to the state in which it received it; MSHTML does not need to save the device context's state prior to passing it to the IHTMLPainter::Draw method.

HTMLPAINTER_SUPPORTS_XFORM

The behavior supports transformations. If a behavior does not support transformations and MSHTML is applying a transformation to its output (for instance, in a zoomed page layout view), its IHTMLPainter::Draw method will not be called and the behavior will not be rendered.

HTMLPAINTER_EXPAND

Not implemented.

HTMLPAINTER_NOSCROLLBITS

Internet Explorer 6 and later. Do not use the device context to perform scroll operations. Specify this flag if the behavior has a fixed background or does not clip its text overflow.
