Reference for the Mosaic class Graphics::AttrSet
The class Graphics::AttrSet provides a container for attributed text operands. It is intended to store the colors, bitmap and font objects needed when the attributed text is drawn. Its function is similar to the of an array of colors, bitmaps and fonts. The class provides properties and methods to access and manage these arrays.
Primarily, the properties Color0 .. Color9, Bitmap0 .. Bitmap9, Font0 .. Font3 are available for the direct access to the corresponding array entries. Thus the set can be initialized by simply assigning values to these properties. In the case, the attributed text expects more colors, fonts or bitmaps, the desired maximum capacity has to be determined explicitly by the method SetMaxNoOfColors(), SetMaxNoOfFonts() and SetMaxNoOfBitmaps(). These methods resize the set accordingly. The additional entries can be modified only via methods SetColor(), SetFont and SetBitmap(). To query the entries the methods GetColor(), GetFont and GetBitmap() are available.

method Resources::Bitmap
GetBitmap
(
arg int32 aBitmapNo
);
The method GetBitmap() returns the bitmap stored in the entry aBitmapNo of this set. The first entry has the number 0, the second 1, and so far. If there is no bitmap stored in the given entry, 'null' is returned.
method color GetColor
(
arg int32 aColorNo
);
The method GetColor() returns the color stored in the entry aColorNo of this set. The first entry has the number 0, the second 1, and so far. If there is no color stored in the given entry, #00000000 is returned.
method Resources::Font GetFont
(
arg int32 aFontNo
);
The method GetFont() returns the font stored in the entry aFontNo of this set. The first entry has the number 0, the second 1, and so far. If there is no font stored in the given entry, 'null' is returned.
method int32 GetMaxNoOfBitmaps();
The method GetMaxNoOfBitmaps() returns the maximum bitmap array capacity of this set. To change the capacity, the method SetMaxNoOfBitmaps() should be used.
method int32 GetMaxNoOfColors();
The method GetMaxNoOfColors() returns the maximum color array capacity of this set. To change the capacity, the method SetMaxNoOfColors() should be used.
method int32 GetMaxNoOfFonts();
The method GetMaxNoOfFonts() returns the maximum font array capacity of this set. To change the capacity, the method SetMaxNoOfFonts() should be used.
method void SetBitmap

arg Resources::Bitmap
aBitmap
);
The method SetBitmap() assigns the given bitmap object aBitmap to the entry aBitmapNo within this set. The first entry has the number 0, the second 1, and so far. Passing 'null' in aBitmap parameter causes the set to forget the bitmap currently stored in this entry. If there is no bitmap entry with the number aBitmapNo in the set, the operation is ignored. The number of available entries can be determined by method SetMaxNoOfBitmaps(). This modification can cause all associated Views::AttrText views to update themselves.
method void SetColor

arg color aColor
);
The method SetColor() assigns the given color aColor to the entry aColorNo within this set. The first entry has the number 0, the second 1, and so far. If there is no color entry with the number aColorNo in the set, the operation is ignored. The number of available entries can be determined by the method SetMaxNoOfColors(). This modification can cause all associated Views::AttrText views to update themselves.
method void SetFont
(
arg int32 aFontNo,
arg Resources::Font
aFont
);
The method SetFont() assigns the given font object aFont to the entry aFontNo within this set. The first entry has the number 0, the second 1, and so far. Passing 'null' in aFont parameter causes the set to forget the font currently stored in this entry. If there is no font entry with the number aFontNo in the set, the operation is ignored. The number of available entries can be determined by method SetMaxNoOfFonts(). This modification can cause all associated Views::AttrText views to update themselves.
method void SetMaxNoOfBitmaps
(
arg int32 aMaxNoOfBitmaps
);
The method SetMaxNoOfBitmaps() changes the maximum bitmap array capacity of this set to the new value aMaxNoOfBitmaps. To query the current capacity the method GetMaxNoOfBitmaps() can be used.
