Example 1 with TabStopSpan

use of jp.sblo.pandora.jota.text.style.TabStopSpan in project Jota-Text-Editor-old by jiro-aqua.

the class Layout method nextTab.

/**
     * Returns the position of the next tab stop after h on the line.
     *
     * @param text the text
     * @param start start of the line
     * @param end limit of the line
     * @param h the current horizontal offset
     * @param tabs the tabs, can be null.  If it is null, any tabs in effect
     * on the line will be used.  If there are no tabs, a default offset
     * will be used to compute the tab stop.
