72 8 DLU per button plus 4 DLU per character.

73 max (32, 6 * text_length). The factor of six is rather empirical, but it
|
|
|
74 works better than 8 which comes from the definition of a DLU. Buttons are
|
|
|
75 spaced with 6 DLU gap. Minimum distance from the button to the left or right
|
|
|
76 dialog edges is 6 DLU, and the distance between the dialog bottom edge and

77 buttons is 7 DLU.

112 Layout algorithm
|
|
|
113 ----------------
|
|
|
114 First we calculate the minimum width of the button row, excluding "from
|
|
|
115 edge" distances. Note that the static control text can be narrower than
|
|
|
116 X_AVE_TEXT only if both text and button row are narrower than that (so,
|
|
|
117 even if text *can* be wrapped into 2 rows narrower than ave width, it is not
|
|
|
118 done). Let WBR denote the width of the button row.
|
|
|
119
|
|
|
120 Next, the width of the static field is determined.
|
|
|
121 First, if all lines of text fit into max (WBR, X_MAX_TEXT), the width of the
|
|
|
122 control is the same as the width of the longest line.
|
|
|
123 Second, if all lines of text are narrower than X_MIN_TEXT, then width of
|
|
|
124 the control is set to X_MIN_TEXT.
|
|
|
125 Otherwise, width is set to max(WBR, X_AVE_TEXT). In this case, line wrapping will
|
|
|
126 happen.
|
|
|
127
|
|
|
128 If width of the text control is larger than that of the button row, then the
|
|
|
129 latter is centered across the dialog, by giving it extra edge
|
|
|
130 margins. Otherwise, minimal margins are given to the button row.
