| 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. | |

| 91 Text distance from left and right edges is the same as for buttons, and the | |
| 92 top margin is 11 DLU. The static control has height of 2 DLU per control | |
| 93 plus 8 DLU per each line of text. Distance between the bottom edge of the | |
| 94 control and the button row is 15 DLU. Minimum width of the static control | |
| 95 is 100 DLU, thus giving minimum dialog weight of 112 DLU. Maximum width is | |
| 96 300 DLU, and, if the text is wider than that, the text is wrapped on the | |
| 97 next line. Each character in the text is considered 4 DLU wide. | |

| 113 Layout algorithm | |
| 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. | |
