calculating widget sizes. Instead of forking a sub-shell to calculate the optimum size for a widget, use a byRef style call-out to set variables in the parent namespace. For example, instead of: size=$( f_dialog_buttonbox_size title btitle msg ) $DIALOG --title title --backtitle btitle --msgbox msg $size The new API replaces the above with the following: f_dialog_buttonbox_size height width title btitle msg $DIALOG --title title --backtitle btitle --msgbox msg $height $width This reduces the number of forks, improves performance, and makes the code more readable by revealing the argument-order for widget sizing. It also makes performing minor adjustments to the calculated values easier as you no longer have to split-out the response (which required knowledge of ordering so was counter-intuitive).
