70 --------------
|
|
71 All buttons have height of 15 DLU. The minimum width for a button is 32 DLU,
|
|
72 but it can be expanded to accommodate its text, so the width is calculated as
|
|
73 8 DLU per button plus 4 DLU per character.
|
|
74 max (32, 6 * text_length). The factor of six is rather empirical, but it
|
|
75 works better than 8 which comes from the definition of a DLU. Buttons are
|
|
76 spaced with 6 DLU gap. Minimum distance from the button to the left or right
|
|
77 dialog edges is 6 DLU, and the distance between the dialog bottom edge and
|
|
78 buttons is 7 DLU.

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