Function Details

DrawClippedText(dc, word, x, y, maxWidth, wordWidth=-1)

Draw the text, clipping at letter boundaries. This is optimized to reduce the number of calls to GetTextExtent by first estimating the length of the word that will fit in the given width.

Note that I did consider some sort of complex quicksearch algorithm to find the right fit, but generally you're dealing with less than 20 or so characters at a time and you can actually guess reasonably accurately even with proportional fonts. This means its probably cheaper to just start walking up or down from the guess, rather than trying to do a quicksearch -alecf

DrawWrappedText(dc, text, rect, measurements=None)

Simple wordwrap - draws the text into the current DC

returns the height of the text that was written

measurements is a FontMeasurements object as returned by Styles.getMeasurements()

SetTextColorsAndFont(grid, attr, dc, isSelected)

Set the text foreground, text background, brush and font into the dc for grids
