The text edit control displays multiple lines of text to the user and allow the user to enter unconstrained text. In contrast to a line edit that is used to enter only one line of text the text edit is the right control for more than one line.
Is this the right control?
- Use text edits for input of unconstrained text with more than one line.
- Don't use a text edit for input of a few words. Use a line edit to enter single lines of text.
- Don't make users scroll unnecessarily; size text boxes to eliminate the need for scrolling.
- Don't put horizontal scroll bars on multi-line text boxes.
- When disabling the text edit, also disable any associated labels and buttons.
- Label every text edit with a descriptive caption to the top left (cf. alignment).
- Create a buddy relation so access keys are assigned.
