70 8 DLU per button plus 4 DLU per character.

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

75 buttons is 7 DLU.

|
111 ----------------
|
|
|
112 First we calculate the minimum width of the button row, excluding "from
|
|
|
113 edge" distances. Note that the static control text can be narrower than
|
|
|
114 X_AVE_TEXT only if both text and button row are narrower than that (so,
|
|
|
115 even if text *can* be wrapped into 2 rows narrower than ave width, it is not
|
|
|
116 done). Let WBR denote the width of the button row.
|
|
|
117
|
|
|
118 Next, the width of the static field is determined.
|
|
|
119 First, if all lines of text fit into max (WBR, X_MAX_TEXT), the width of the
|
|
|
120 control is the same as the width of the longest line.
|
|
|
121 Second, if all lines of text are narrower than X_MIN_TEXT, then width of
|
|
|
122 the control is set to X_MIN_TEXT.
|
|
|
123 Otherwise, width is set to max(WBR, X_AVE_TEXT). In this case, line wrapping will
|
|
|
124 happen.
|
|
|
125
|
|
|
126 If width of the text control is larger than that of the button row, then the
|
|
|
127 latter is centered across the dialog, by giving it extra edge
|
|
|
128 margins. Otherwise, minimal margins are given to the button row.
