*
* So to create a text buffer window which takes the top 40% of the original
* window's space, you would execute
- * <informalexample><programlisting>
- * newwin = #glk_window_open(win, #winmethod_Above | #winmethod_Proportional, 40, #wintype_TextBuffer, 0);
- * </programlisting></informalexample>
+ * |[ newwin = #glk_window_open(win, #winmethod_Above | #winmethod_Proportional, 40, #wintype_TextBuffer, 0); ]|
*
* To create a text grid which is always five lines high, at the bottom of the
* original window, you would do
- * <informalexample><programlisting>
- * newwin = #glk_window_open(win, #winmethod_Below | #winmethod_Fixed, 5, #wintype_TextGrid, 0);
- * </programlisting></informalexample>
+ * |[ newwin = #glk_window_open(win, #winmethod_Below | #winmethod_Fixed, 5, #wintype_TextGrid, 0); ]|
*
* Note that the meaning of the @size argument depends on the @method argument.
* If the method is #winmethod_Fixed, it also depends on the @wintype argument.
* What happens when there is a conflict? The rules are simple. Size control
* always flows down the tree, and the player is at the top. Let's bring out an
* example:
- * <mediaobject><textobject><phrase>Screen shot 5</phrase></textobject>
- * </mediaobject>
+ * <informaltable frame="none"><tgroup cols="2"><tbody><row>
+ * <entry><mediaobject><imageobject><imagedata fileref="fig5-7a.png"/>
+ * </imageobject></mediaobject></entry>
+ * <entry><mediaobject><textobject><literallayout class="monospaced">
+ * O
+ * / \
+ * O B
+ * / \
+ * A C
+ * </literallayout></textobject></mediaobject></entry>
+ * </row></tbody></tgroup></informaltable>
*
* First we split A into A and B, with a 50% proportional split. Then we split
* A into A and C, with C above, C being a text grid window, and C gets a fixed
* of the 50% it had before.
*
* Now the player stretches the window vertically.
- * <mediaobject><textobject><phrase>Screen shot 6</phrase></textobject>
- * </mediaobject>
+ * <informalfigure><mediaobject><imageobject><imagedata fileref="fig6.png"/>
+ * </imageobject></mediaobject></informalfigure>
*
* The library figures: the topmost split, the original A/B split, is 50-50. So
* B gets half the screen space, and the pair window next to it (the lower
* <quote>O</quote>. C gets two rows; A gets the rest. All done.
*
* Then the user maliciously starts squeezing the window down, in stages:
- * <mediaobject id="chimara-Figure-Squeezing-Window"><textobject><phrase>
- * Screen shot 7</phrase></textobject></mediaobject>
+ * <informaltable frame="none"><tgroup cols="5"><tbody><row valign="top">
+ * <entry><mediaobject><imageobject><imagedata fileref="fig5-7a.png"/>
+ * </imageobject></mediaobject></entry>
+ * <entry><mediaobject><imageobject><imagedata fileref="fig7b.png"/>

+ * <entry><mediaobject><imageobject><imagedata fileref="fig7e.png"/>
+ * </imageobject></mediaobject></entry>
+ * </row></tbody></tgroup></informaltable>
*
* The logic remains the same. B always gets half the space. At stage 3,
* there's no room left for A, so it winds up with zero height. Nothing
* is stored by a window's parent, not the window itself; and a constraint
* consists of a pointer to a key window plus a size value.
