Motif and CDE 2.1 Style Guide Certification Checklist

Text Field (Abstract Control)

[ ]
Provide a text field when you display a sequence of characters that the user can manipulate as a unit or in which you want to allow the user to navigate and manipulate at least one subsequence of characters.

[ ]
Organize elements of a text field into complete words as the first level of a multilevel hierarchy (for example, double-clicking SELECT on a word should select the word). The boundary of a word is defined by a language's characters in the text field.

[ ]
Support point and range selection techniques and multilevel selection techniques for text.

[ ]
If supporting area techniques, provide a choice that allows the user to switch between use of range and area techniques.

[ ]
When the user presses Ctrl Space in a text field, it should have the same effect as a keyboard-based point selection technique.

[ ]
When the user presses Ctrl Shift Space in a text field, it should have the same effect as a keyboard-based range adjust click selection technique.

[ ]
If word-wrapping is used and as a result multiple lines are displayed in a text field, treat each visual line as a separate line for navigation operations.

[ ]
The directional keys should operate in the following manner:

^
In a multiline text field, move the cursor up one visually displayed line.

V
In a multiline text field, move the cursor down one visually displayed line.

<
Move the cursor left one character.

>
Move the cursor right one character.

[ ]
The directional keys augmented by Ctrl should operate as follows:

Ctrl <
In a text field with multiple words, move the cursor to the beginning of the word to the left.

Ctrl >
In a text field with multiple words, move the cursor to the beginning of the word to the right.

[ ]
When the user presses a directional key to move the cursor horizontally, wrap the text cursor from the end of one row to the beginning of the next row (and vice versa). Do not, however, wrap between the beginning and the end of the text field.

[ ]
The navigational keys should operate as follows:

Home (or Begin)
Place the cursor at the beginning of the current line.

END
Place the cursor at the end of the current line.

Ctrl Home (or Ctrl Begin)
Place the cursor before the first character.

Ctrl End
Place the cursor after the last character.

[ ]
When nontextual elements that have no internal navigation (such as icons or choices) are included as elements in text and laid out as characters, navigation should perform in the following ways:

  1. When the user is navigating through text, a text cursor should always stop in between adjacent characters, between a character and a nontextual element, and between two adjacent nontextual elements.

  2. Use an element cursor to indicate that focus is on a nontextual element.

  3. When a text cursor is immediately to the left or right of a nontextual element, allow > and < to remove the text cursor and move focus to the nontextual element.

  4. When an element cursor is on a nontextual element, allow > and < to remove focus from the nontextual element and place the text cursor to the right or left of the element.

  5. Treat nontextual elements as words with regard to multilevel navigation. That is, if the cursor is on the nontextual element or immediately before it and the user presses Shift >, move the text cursor to the beginning of the word (or nontextual element) following it. If the cursor is on the nontextual element or immediately after it and the user presses Shift <, move the text cursor immediately before it.

    6. [ ]
    Treat nontextual elements included with characters in text either as selectable or nonselectable consistently within the scope. If they are treated as nonselectable, exclude them from selections that physically contain them.

    [ ]
    When active regions (regions of text that act like action choices) are allowed in a text field, use the following rules:

    1. Active regions must be highlighted to indicate their boundaries and must not overlap.

    2. When the user clicks the SELECT button within an active region, invoke the action associated with that region and move the text cursor to the pointer location.

    3. When the user presses the SELECT button within an active region without clicking (including releasing SELECT past the threshold time), select the active region.

    4. When the user clicks Ctrl SELECT within an active region, move the text cursor to the location clicked, but do not invoke the action associated with the region.

    5. When the text cursor is within an active region, the default action should be invoking the action that corresponds to the region.

    6. If the user can edit the text field, all characters typed have their usual effect regardless of whether or not the text cursor is within an active region. For example, when the user presses Enter in an editable multiline text control, insert a new line in the active region. When the user presses Ctrl Enter, invoke the default action, which invokes the action that corresponds to the region.
