@brief Create a new frame.
The mframe () function creates a new frame with parameters listed
- in $PLIST.
+ in $PLIST which may be @c NULL.
The recognized keys in $PLIST are window system dependent.
<ul>
- <li> #Mface, the value type must be <tt>(MFace *)</tt>.
+ <li> #Mdevice, the value must be one of #Mx, #Mgd, and #Mnil.
+
+ If the value is #Mx, the frame is for X Window System. The
+ argument #MDrawWindow specified together with the frame must be of
+ type @c Window. The frame is both readable and writable, thus all
+ GUI functions can be used.
+
+ If the value is #Mgd, the frame is for an image object of GD
+ library. The argument #MDrawWindow specified together with the
+ frame must be of type @c gdImagePtr. The frame is writable
+ only, thus functions minput_XXX can't be used for the frame.
+
+ If the value is #Mnil, the frame is for a null device. The frame
+ is not writable nor readable, thus functions mdraw_XXX that
+ require the argument #MDrawWindow and functions minput_XXX can't
+ be used for the frame.
+
+ <li> #Mface, the value must be a pointer to #MFace.
The value is used as the default face of the frame.
</ul>
- In addition, in the m17n-X library, the following keys are
- recognized. They are to specify the root window and the depth of
- drawables that can be used with the frame.
+ In addition, if the value of the key #Mdevice is #Mx, the
+ following keys are recognized. They are to specify the root
+ window and the depth of drawables that can be used with the frame.
<ul>
- <li> #Mdrawable, the value type must be <tt>Drawable</tt>
+ <li> #Mdrawable, the value type must be <tt>Drawable</tt>.
A parameter of key #Mdisplay must also be specified. The
created frame can be used for drawables whose root window and
newly created frame. Otherwise, it returns @c NULL. */
