panda3d.core.FontPool

class FontPool

This is the preferred interface for loading fonts for the TextNode system. It is similar to ModelPool and TexturePool in that it unifies references to the same filename.

Inheritance diagram

static hasFont(filename: str) → bool

Returns true if the font has ever been loaded, false otherwise.

static verifyFont(filename: str) → bool

Loads the given filename up into a font, if it has not already been loaded, and returns true to indicate success, or false to indicate failure. If this returns true, it is guaranteed that a subsequent call to loadFont() with the same font name will return a valid Font pointer.

static loadFont(filename: str) → TextFont

Loads the given filename up into a font, if it has not already been loaded, and returns the new font. If a font with the same filename was previously loaded, returns that one instead. If the font file cannot be found, returns NULL.

Return type

TextFont

static addFont(filename: str, font: TextFont) → None

Adds the indicated already-loaded font to the pool. The font will always replace any previously-loaded font in the pool that had the same filename.

static releaseFont(filename: str) → None

Removes the indicated font from the pool, indicating it will never be loaded again; the font may then be freed. If this function is never called, a reference count will be maintained on every font every loaded, and fonts will never be freed.

static releaseAllFonts() → None

Releases all fonts in the pool and restores the pool to the empty state.

static garbageCollect() → int

Releases only those fonts in the pool that have a reference count of exactly 1; i.e. only those fonts that are not being used outside of the pool. Returns the number of fonts released.

static listContents(out: ostream) → None

Lists the contents of the font pool to the indicated output stream.

static write(out: ostream) → None

Lists the contents of the font pool to the indicated output stream.
