Description

The titled pane makes its title decoration from a title-pane and the message decoration from a message-pane.

The text of the title-pane is passed via the titled-object initarg title and the text of the message-pane is passed via the titled-object initarg message .

The initargs and font for the title-pane are passed via the titled-object initargs title-args and title-font respectively.

title-gap specifies the size in pixels of the gap between the title and the pane. The default value of title-gap is 3.

For subclasses other than interface, the font used for the message can be found by titled-object-message-font and set by (setf titled-object-message-font).

message-gap specifies the size in pixels of the gap between the message and the pane. The default value of message-gap is 3.

The message is always placed below the pane, but the title's position can be adjusted by specifying title-position which can be any of the following.

:left

Place the title to the left of the pane.

:right

Place the title to the right of the pane.

:top

Place the title above the pane.

:bottom

Place the title below the pane.

:frame

Place the title in a frame (like a groupbox) around the pane.

The title-adjust slot is used to adjust the title so that it is left justified, right justified or centered. The value of title-adjust can be any of the values accepted by the function pane-adjusted-offset, which are :left, :right, :top, :bottom, :center and :centre.

Note: title-adjust cannot handle both x and y. It is designed for cases like this:

(capi:contain
 (make-instance 'capi:list-panel
                :items '(1 2 3 4 5)
                :title "Temp"
                :title-position :left
                :title-adjust :center
                :title-args 
                '(:visible-min-width (:character 12))))

mnemonic-title offers an alternate way to provide the pane's title, and with a mnemonic. It takes effect only for button-panel, list-panel, list-view, option-pane, output-pane, progress-bar, scroll-bar, slider, text-input-pane, text-input-range, tree-view and their subclasses, and is interpreted as described for menu.

Note: titles and mnemonic titles can now be added in a grid-layout.

Compatibility note

titled-object corresponds to the LispWorks 4.1 class titled-pane. For backwards compatibility the accessors titled-pane-title and titled-pane-message, including setf methods, are provided. These simply trampoline to titled-object-title and titled-object-message, and may not be supported in future releases.

Example

Try each of these examples to see some of the effects that titled panes can produce. Note that text-input-pane is a subclass of titled-object, and that it has a default title-position of :left.

(capi:contain (make-instance 'capi:text-input-pane))
(capi:contain (make-instance 'capi:text-input-pane
                              :title "Enter some text:"))
(capi:contain (make-instance 
               'capi:text-input-pane
               :title "Enter some text:"
               :title-position :top))
(capi:contain (make-instance 'capi:text-input-pane
                              :title "Enter some text:"
                              :title-position :top
                              :title-adjust :center))
(capi:contain (make-instance 'capi:text-input-pane
                             :title "Enter some text:"
                             :title-position :top
                             :title-adjust :right))
(capi:contain (make-instance 'capi:text-input-pane
                              :message "A message"))
(capi:contain (make-instance 'capi:text-input-pane
                              :message "A message"
                              :title "Enter some text:"))
(capi:contain (make-instance 'capi:text-input-pane
                             :title "Enter some text:"
                             :title-args
                              '(:foreground :red)))
