SA_SysFont

Tag start for OpenScreenTagList() Selects one of the preferences system fonts: 0 - old DefaultFont, fixed-width 1 - WB Screen preferred font

Declaration

Source position: intuition.pas line 2038

const SA_SysFont = SA_Dummy + $000C;

Description

Alternative to SA_Font. Selects one of the preferences system fonts. Data is a LongWord, with the following values defined:

0: Open screen with the user's preferred fixed width font (the default).
1: Open screen with the user's preferred font, which may be proportional.

The Workbench screen is opened with [SA_SysFont, 1]. Table summarizes how the font selected at OpenScreen() time effects subsequent text operations in screens and windows.

	What you tell OpenScreen()	Screen font	Window.RPort font
A.	TNewScreen.Font = myfont	myfont	myfont
B.	TNewScreen.Font = nil	AGraphics.TGfxBase.DefaultFont	AGraphics.TGfxBase.DefaultFont
C.	[SA_Font, myfont]	myfont	myfont
D.	[SA_SysFont, 0]	AGraphics.TGfxBase.DefaultFont	AGraphics.TGfxBase.DefaultFont
E.	[SA_SysFont, 1]	Font Prefs Screen text	AGraphics.TGfxBase.DefaultFont

Notes:

A and B are the options that existed in V34 and earlier OS versions.
C and D are tags in Release 2 equivalent to A and B respectively.
E is a new option for V36. The Workbench screen uses this option.
For `myfont', any font may be used including a proportional one. This is true under all releases of the OS.
AGraphics.TGfxBase.DefaultFont is always monospace. (This is the "System Default Text" from Font Preferences.)
Font Prefs Screen text (the "Screen Text" choice from Font Preferences) can be monospace or proportional.

The screen's font may not legally be changed after a screen is opened. The menu bar, window titles, menu items, and the contents of a string gadget all use the screen's font. The font used for menu items can be overridden in the menu item's IntuiText structure. Under V36 and higher, the font used in a string gadget can be overridden through the StringExtend structure. The font of the menu bar and window titles cannot be overridden.

The Window.RPort font shown above is the initial font that Intuition sets in your window's RastPort. It is legal to change that subsequently with SetFont(). IntuiText rendered into a window (either through PrintIText() or as a TGadget.GadgetText) defaults to the window's RastPort font, but can be overridden using its TGadget.TITextFont field. Text rendered with the graphics library call GfxText() uses the window's RastPort font.
