const nsFont* nsPresContext::GetDefaultFont ( PRUint8 aFontID ) const

Get the default font corresponding to the given ID.

This object is read-only, you must copy the font to modify it.

When aFontID is kPresContext_DefaultVariableFontID or kPresContext_DefaultFixedFontID (which equals kGenericFont_moz_fixed, which is used for the -moz-fixed generic), the nsFont returned has its name as a CSS generic family (serif or sans-serif for the former, monospace for the latter), and its size as the default font size for variable or fixed fonts for the pres context's language group.

For aFontID corresponds to a CSS Generic, the nsFont returned has its name as the name or names of the fonts in the user's preferences for the given generic and the pres context's language group, and its size set to the default variable font size.

Get the font metrics for a given font.

If aUseUserFontSet is false, don't build or use the user font set. This is intended only for nsRuleNode::CalcLengthWithInitialFont (which is used from media query matching, which is in turn called when building the user font set).

float nsPresContext::GetPageScale ( ) [inline]

Get/set the print scaling level; used by nsPageFrame to scale up pages.

Set safe to call before reflow, get guaranteed to be set properly after reflow.

If we have a presshell, and if the given content's current document is the same as our presshell's document, return the content's primary frame.

Otherwise, return null. Only use this if you care about which presshell the primary frame is in.

float nsPresContext::GetPrintPreviewScale ( ) [inline]

Get/set the scaling facor to use when rendering the pages for print preview.

Only safe to get after print preview set up; safe to set anytime. This is a scaling factor for the display of the print preview. It does not affect layout. It only affects the size of the onscreen pages in print preview. XXX Temporary: see http://wiki.mozilla.org/Gecko:PrintPreview

nsIPrintSettings* nsPresContext::GetPrintSettings ( ) [inline]

void nsPresContext::RebuildAllStyleData ( nsChangeHint aExtraHint )

Rebuilds all style data by throwing out the old rule tree and building a new one, and additionally applying aExtraHint (which must not contain nsChangeHint_ReconstructFrame) to the root frame.

Also rebuild the user font set.

void nsPresContext::RebuildUserFontSet ( )

void nsPresContext::ReflowStarted ( PRBool aInterruptible )

Notify the prescontext that the presshell is about to reflow a reflow root.

The single argument indicates whether this reflow should be interruptible. If aInterruptible is false then CheckForInterrupt and HasPendingInterrupt will always return false. If aInterruptible is true then CheckForInterrupt will return true when a pending event is detected. This is for use by the presshell only. Reflow code wanting to prevent interrupts should use InterruptPreventer.

void nsPresContext::SetImageLoaders	(	nsIFrame *	aTargetFrame,
		ImageLoadType	aType,

Set the list of image loaders that track invalidation for a specific frame and type of image.

This list will replace any previous list for that frame and image type (and null will remove any previous list).
