Labels are intended to be small text elements which can be added to the worksheet. Since it is currently not possible to edit the text field, these widgets are not currently usable. The properties of the border and background of the widget can be changed but, because the word "Label" is always present, the rectangle drawing element, presented in Section 9.4.3 ― Drawing Rectangles. will be more useful.
The properties of the label can be altered with the Properties menu item in the context menu which appears when the mouse cursor is placed over the label and one of the secondary mouse buttons is pressed.
The label outline color and width, as well as the background, "fill", color can be changed.
The color of the label outline can be altered by moving the mouse pointer over the button with the icon of a small, black, downward pointing arrow and then clicking with the primary mouse button. This will open up a panel with a number of standard colors presented as small squares. Any of these colors can be selected by moving the mouse pointer over the desired color and pressing once with the primary mouse button. Alternatively, a custom color can be chosen by clicking on the button at the bottom of the panel. This will open up the color chooser dialog. In this dialog colors can be defined using the numeric boxes or can be selected using the color triangle. The color can be selected by Clicking on the outer circle while the darkness or lightness can be selected by clicking inside the triangle. Once the desired color has been configured, this color can be used for the label outline by clicking on the OK button.
The border width can be changed either by typing a new number into the text box or by using the up and down arrows to increment or decrement the width number.
The color of the background fill can be changed in the same way as the color of the outline border, which was explained above.
