Editors and Selectors

Detailed Description

Use an editor or selector when the user should enter or pick a value.

LineEdit is a single-line text field. An entry shows the text, a caret, and an optional selection. Placeholder text can appear when the field is empty.

SpinBox is an integer in a range. An entry shows the number. Up and down controls step it. A style may merge those controls with the entry or place them beside it.

ComboBox is a value chosen from a list, or typed when the box is editable. An entry shows the current text. A button opens a popup list.

Slider is a value chosen along a range by dragging. A track shows the range. A handle shows the current value.

LineEditor is not a control. It stores the text, caret, and scroll of one line. LineEdit, SpinBox, and ComboBox use it.

Appearance follows the application style. On invalidate the control binds a family renderer through a styler. Widget-local brushes, pens, colors, fonts, and setRenderer() overlay that style without replacing it.
