特性文档编制

font : font

The font of the control.

This property was introduced in QtQuick.Controls.Styles 1.3.

frame : Component

The background frame for the menu popup.

The Menu will resize the frame to its contents plus the padding.

itemDelegate : 对象

The object containing the menu item subcontrol components. These subcontrols are used for normal menu items only, i.e. not for separators or scroll indicators.

The subcontrols are:

itemDelegate.background : Component
The menu item background component.

Its appearance generally changes with styleData.selected and styleData.enabled .

The default implementation shows only when the item is enabled and selected. It remains invisible otherwise.
itemDelegate.label : Component
Component for the actual text label.

The text itself is fetched from styleData.text , and its appearance should depend on styleData.enabled and styleData.selected .

若 styleData.underlineMnemonic is true, the label should underline its mnemonic character. formatMnemonic provides the default formatting.
itemDelegate.submenuIndicator : Component
It indicates that the current menu item is a submenu.

Only used when styleData.type 等于 MenuItemType.Menu .
itemDelegate.shortcut : Component
Displays the shortcut attached to the menu item.

Only used when styleData.shortcut is not empty.
itemDelegate.checkmarkIndicator : Component
Will be used when styleData.checkable is true and its appearance may depend on styleData.exclusive , i.e., whether it will behave like a checkbox or a radio button. Use styleData.checked for the checked state.

注意： This property cannot be overwritten although all of the subcontrol properties can.

scrollIndicator : Component

Component for the scroll indicator menu item.

Will be used when styleData.type 等于 MenuItemType.ScrollIndicator . Its appearance should follow styleData.scrollerDirection .

This is the item added at the top and bottom of the menu popup when its contents won't fit the screen to indicate more content is available in the direction of the arrow.

separator : Component

Component for the separator menu item.

Will be used when styleData.type 等于 MenuItemType.Separator .

submenuOverlap : int

The amount of pixels by which a submenu popup overlaps horizontally its parent menu.

submenuPopupDelay : int

The number of milliseconds to wait before opening a submenu.

方法文档编制

string formatMnemonic ( string text , bool underline = false)

Returns a rich-text string to render mnemonics for a given menu item.

The mnemonic character is prefixed by an ampersand in the original string.

传递 true for underline will underline the mnemonic character (e.g., formatMnemonic("&Open...", true) 将返回 "<u>O</u>pen..." ). Passing false for underline will return the plain text form (e.g., formatMnemonic("&Open...", false) 将返回 "Open..." ).
