    • Method Detail

      • setColumns

        @Deprecated
public void setColumns​(int columns)
        Deprecated.
        As of 7.0. "Columns" does not reflect the exact number of characters that will be displayed. It is better to use setWidth together with "em" to control the width of the field.
        Sets the width of the component so that it displays approximately the given number of letters in each of the two selects.

        Calling setColumns(10); is roughly equivalent to calling setWidth((10*2+4)+"10em");

        Parameters:
        columns - the number of columns to set.

      • getColumns

        @Deprecated
public int getColumns()
        Deprecated.
        As of 7.0. "Columns" does not reflect the exact number of characters that will be displayed. It is better to use setWidth together with "em" to control the width of the field.
        Gets the number of columns for the component.

        setColumns(int)

      • getRows

        public int getRows()

      • setRows

        public void setRows​(int rows)
        Sets the number of rows in the editor. If the number of rows is set to 0, the actual number of displayed rows is determined implicitly by the adapter.

        If a height if set (using AbstractComponent.setHeight(String) or #setHeight(float, int)) it overrides the number of rows. Leave the height undefined to use this method. This is the opposite of how setColumns(int) work.

        Parameters:
        rows - the number of rows to set.
