tk2fonts: Edit a matrix or data frame in spreadsheet-like editor

Description

A tkTable widget is used to display and edit a matrix or data frame. One can edit entries, add or delete rows and columns, ....

Usage

tk2font.get(font, what = c("family", "size", "bold", "italic")) tk2font.set(font, settings) tk2font.setstyle(text = TRUE, system = FALSE, default.styles = FALSE)

Arguments

font
the name of one or several cached Tk font.
what
a list of font characteristics to get: 'family', 'size', 'bold', 'italic', 'underline' and/or 'overstrike'. By default, everything except 'underline' and 'overstrike'.
settings
settings of fonts. There are two forms possibles: (1) a vector of character strings of same length as font with Tk fonts description like '-family Times -size 12 -weight bold', for instance, or (2) a list of font characteristics (list with components 'family', 'size', 'bold', 'italic', 'underline' and 'overstrike').
text
do we synchronise text Tk fonts (text, titles, and fixed-font text) with current settings, as in .Fonts in SciViews:TempEnv?
system
do we synchronise system Tk fonts (widgets, window caption, menus, tooltips, ...) with current system configuration? This is highly platform dependent. Currently, system settings are gathered only under Windows, thanks to the winSystemFonts() function.
default.styles
do we add .fontsStyleXXX in SciViews:TempEnv, where XXX is one of the four default styles: 'Classic', 'Alternate', 'Presentation' or 'Fancy'.

Value

tk2font.get() retrieves a list with font characteristics (same format as the settings argument) for the first Tk font found in its font argument, or "" if the font is not found. tk2font.set() changes current font settings or, possibly, create the Tk font. tk2font.setstyle() changes the current Tk fonts settings according to actual system and/or text configuration fonts.
