詳細描述

The command link is a new control that was introduced by Windows Vista. Its intended use is similar to that of a radio button in that it is used to choose between a set of mutually exclusive options. Command link buttons should not be used by themselves but rather as an alternative to radio buttons in Wizards and dialogs and makes pressing the "next" button redundant. The appearance is generally similar to that of a flat pushbutton, but it allows for a descriptive text in addition to the normal button text. By default it will also carry an arrow icon, indicating that pressing the control will open another window or page.

描述 : QString

此特性保持描述性標簽,以補充按鈕文本

設置此特性將在按鈕上設置描述性文本,以補充文本標簽。這通常會以比首要文本更小的字體顯示。

訪問函數:

QString 描述 () const
void setDescription (const QString & 描述 )

flat : bool

此特性確定按鈕是被顯示為平闆,還是帶邊框。

默認情況下,此特性被設為 false。

訪問函數:

bool isFlat () const
void setFlat ( bool )
