-
- This guide presents style considerations you can follow when
- designing Borland Windows Custom Control (BWCC) dialog boxes for
- your Windows-based software.
-
-
- 1 Layout issues
- ----------------------
-
- Before you begin designing your dialogs, you should be aware of
- some basic design considerations.
-
-
- 1.1 Panels
- ---------------
-
- Each dialog box has two panels: a Main panel and an Action panel.
- The Main panel contains all the elements that are read or
- modified when the dialog box is open. The Action panel contains
- the push buttons, usually OK, Cancel, and Help.
-
-
- 1.2 Fonts
- --------------
-
- Borland dialogs use 8 point Helvetica Bold. The BWCC dialog
- controls look best when you use this font. An 8 point font is
- small; using it keeps the size of the your dialogs from growing
- too big. Of course, you can use other fonts for other custom
- controls.
-
-
- 1.3 Group Boxes
- --------------------
-
- Collect all options that appear in the Main panel into BWCC group
- boxes. For example, place a group of related check boxes in a
- group box. You should place each single control, such as a file
- name text box or combo box, in a group box also. You won't have
- to do this with a Borland list box because a list box draws its
- own group box.
-
-
- 1.4 Push buttons
- ---------------------
-
- The following are style considerations for push buttons:
-
- - Borland's push buttons use glyphs (small bitmapped images). For
- example, a question-mark glyph is used on the Help push button.
- Place the glyph inside the button on the left side.
-
- - Use Helvetica (normal, not bold) for the button's text and
- justify it to the right.
-
- - Make each push button 39 pixels high for VGA resolution and 30
- pixels high for EGA resolution.
-
- - Most push buttons are 63 pixels wide in both VGA and EGA
- resolution. Although you can make a button wider to prevent the
- text and image from overlapping or looking too crowded, you
- should try to restrict the width to 63 pixels if possible.
-
-
- 2 Dimension and alignment guidelines
- -------------------------------------------
-
- The following sections present guidelines for laying out the
- controls in a BWCC dialog box.
-
-
- 2.1 Arranging the panels
- -----------------------------
-
- The Main panel of your dialog should be as large as necessary to
- contain all the required controls. The Action panel should be
- just big enough to contain the push buttons; you can place it
- either at the bottom or the right side of the dialog.
-
- Your finished dialog should be relatively square. If the Main
- panel is wider than it is tall, put the Action panel along the
- bottom of your dialog. If the Main panel is taller than it is
- wide, put the Action panel on the right side.
-
-
- 2.2 Main panel
- -------------------
-
- You may arrange the group boxes on the Main panel in either a
- single column or row, or in an array. Here are some guidelines to
- arranging group boxes on the Main panel. You should treat group
- titles as part of the group boxes.
-
- - Space group boxes 8 dialog units apart, both vertically and
- horizontally.
-
- - Leave a margin of 8 dialog units from all edges of the dialog
- to the nearest group box.
-
- - In a column of group boxes, make all group boxes the same
- width. The width should accommodate the widest item or title.
- Widen the other group boxes to match.
-
- - In a row of group boxes, you may vary the group box heights.
- Align the tops of the group boxes and let the bottoms of the
- group boxes vary.
-
- - If some of the group boxes you want to align in a row have
- titles and some don't, align the top of the recessed group
- boxes with each other, not with the title rectangles. For these
- mixed groups of boxes, the margin above group boxes without
- titles should include the space for a title.
-
- - If some of the group boxes you want to align in a row are
- taller than others, compute the bottom margin using the tallest
- group box.
-
-
- 2.3 Horizontal action panel
- --------------------------------
-
- An Action panel that appears at the bottom of a dialog is a
- horizontal Action panel. It extends the full width of the dialog.
- Here are the guidelines:
-
- - Make the Action panel tall enough to contain the push buttons
- while leaving a margin of 8 dialog units above and 8 dialog
- units below the push buttons.
-
- - Distribute the push buttons evenly along the Action panel,
- leaving a minimum of 8 dialog units between the buttons
- themselves and between the buttons and the left and right edges
- of the dialog.
-
- Try to use the same number of dialog units between each button
- and between the buttons and the left and right edges of the
- dialog. You may put more space between the buttons than between
- the buttons and the edges of the dialog, if necessary, but the
- two margin spaces should be equal and the spaces between the
- buttons should be equal.
-
-
- 2.4 Vertical action panel
- ------------------------------
-
- An Action panel that appears at the right side of a dialog is a
- vertical Action panel. It extends the full height of the dialog.
- Here are the guidelines:
-
- - Make the Action panel wide enough to contain the push buttons
- while leaving a margin of 8 dialog units to right and 8 dialog
- units to the left of the push buttons.
-
- - Distribute the push buttons evenly along the Action panel,
- leaving a minimum of 8 dialog units between the buttons
- themselves and between the buttons and the top and bottom edges
- of the dialog.
-
- Try to use the same number of dialog units between each button
- and between the buttons and the top and bottom edges of the
- dialog. You may put more space between the buttons than between
- the buttons and the edges of the dialog, if necessary, but the
- two margin spaces must be equal and the spaces between the
- buttons must be equal.
-
-
- 2.5 Group box titles
- -------------------------
-
- A group box title identifies what a group box contains. By
- default, a group box title in a Borland dialog has a gray
- background. The following are the guidelines for group boxes:
-
- - If a group box contains multiple controls, place the group box
- title just above and touching the top edge of the group box.
-
- - If a group box contains a single check box, place the group box
- title just above and touching the top edge of the group box.
-
- - If a group box contains a single text box or combo box control,
- either put the title to the left of the control and 4 units
- from the edge of the group box or put it above the control,
- whichever you prefer.
-
- - If a group box contains two or more editable text fields or
- combo boxes or both, precede each with a short label.
-
- - Align group box titles above the recessed group boxes.
-
- - Make all group box titles 9 units high.
-
- - Make the titles the same width as the group boxes, including
- the beveled sides.
-
-
- 2.6 Group box elements
- ---------------------------
-
- These suggestions will help you arrange the elements within a
- group box:
-
- - Distribute controls within a group box vertically every 13
- units from the bottom of one line of text to the bottom of the
- next.
-
- - Justify the controls to the left.
-
- - Make the left and right margins between the edges of the group
- box and the widest control within it all 4 dialog units wide.
-
- - Make the margin between the top of the group box and the first
- control in the group 4 dialog units.
-
- - Make the margin between the bottom of the group box and the
- last control in the group 4 dialog units.
-
- - If a group box contains two or more editable text fields or
- combo boxes or both, make them the same width. Space them so
- that the bottom of one is 13 units apart from the bottom of the
- next one. Right-justify these controls in the group box 4 units
- from the right edge. Left-justify the titles, leaving a 4 unit
- margin. Make the group box wide enough to leave 4 units between
- the longest title and its control.
-
-
- 2.7 Message boxes
- ----------------------
-
- Like dialog boxes, messages boxes have two panels: a Main panel
- and an Action panel.
-
- The Main panel of the message box is filled with a single group
- box. The group box contains a message glyph and a text region.
-
- Here are the guidelines for designing a message box:
-
- - Put the glyph on the left side of the group box.
-
- - Leave a margin of 8 dialog units on all four sides of the group
- box.
-
- - Space the message glyph and the text region 8 dialog units
- apart.
-
- - Center the text region vertically, leaving at least 8 dialog
- units between the top and bottom of the text region and the top
- and bottom edges of the dialog.
-
- - Place the Action panel at the bottom of your dialog.
-
- - Test this layout using your longest message string. If
- necessary, resize the text region accordingly.
-
-
- 2.8 Examining your dialog
- ------------------------------
-
- When Windows calculates dialog units, it rounds the computation.
- Rounding errors may affect the appearance of your dialog. Examine
- your dialog carefully. These problems have been noted:
-
- - A crack between the title text and the top of a gray group box
-
- - Obvious uneven spacing in a vertical group of radio buttons or
- check boxes
-
- - An inconsistent border width in exposed panel areas
-
- Usually, making an adjustment of 1 dialog unit will fix these
- problems. Occasionally in a large group of repeating controls,
- two or more rounding errors can occur. Sometimes making an
- adjustment can improve the layout of your dialog; at other times
- you may decide not to make any changes. Use your best judgment.
-
- You can't tell how text in controls will appear when you are
- designing your dialog. Editable text, large static text fields,
- and combo boxes fall into this category. You may have to modify
- your original design to be sure text appears correctly without
- being clipped at run time.
-
-
- 2.9 Using standard push buttons
- ------------------------------------
-
- The Action panel push buttons usually indicate the end of a
- user's work with a dialog, but can also serve as a major
- departure from the function of the dialog, such as bringing up
- Help with the Help button.
-
- An application can also have push buttons that don't result in
- closure. With these buttons, the user wants to perform specific
- actions but continue working with the dialog. Groups of these
- buttons often have related functions.
-
- For example, a Search dialog box could have Action panel buttons
- for Find Next and Replace.
-
- The guidelines for standard buttons are as follows:
-
- - Put these push buttons on the Main panel rather than the Action
- panel.
-
- - Don't put these push buttons in a group box. Place them
- directly on the surface of the Main panel.
-
- - Make all push buttons in a group the same width. They should be
- just wide enough to accommodate the widest text string.
-
- - Make the buttons 14 dialog units in height.
-
- - Try to restrict text to 20 characters or less.
-
- - Lay the buttons out in either a row or a column, depending on
- what looks best in your dialog.
-
- - Leave 8 dialog units to the left and right of a column of push
- buttons. The vertical space between the buttons and any other
- controls or borders above or below the buttons should be equal.
-
- - Leave 8 dialog units above and below a row of push buttons. The
- horizontal space between the buttons and any other controls or
- borders to the left or right of them should be equal.
