详细描述

The ColorDialog type provides a QML API for color dialogs.

To show a color dialog, construct an instance of ColorDialog, set the desired properties, and call open ()。 selectedColor property can be used to determine the initially selected color in the dialog.

MenuItem {
    text: qsTr("Color")
    onTriggered: colorDialog.open()
}
ColorDialog {
    id: colorDialog
    selectedColor: document.color
    onAccepted: document.color = selectedColor
}
MyDocument {
    id: document
}
					

可用性

A native platform color dialog is currently available on the following platforms:

  • iOS
  • Linux (when running with the GTK+ platform theme)
  • macOS

Qt Quick Dialogs uses a Qt Quick implementation as a fallback on platforms that do not have a native implementation available.

特性文档编制

options : flags

This property holds the various options that affect the look and feel of the dialog.

默认情况下,所有选项是被禁用的。

Options should be set before showing the dialog. Setting them while the dialog is visible is not guaranteed to have an immediate effect on the dialog (depending on the option and on the platform).

Available options:

常量 描述
ColorDialog.ShowAlphaChannel Show a slider and additional input fields for the alpha value.
ColorDialog.NoButtons 不显示 Open and Cancel buttons (useful for "live dialogs").
ColorDialog.DontUseNativeDialog Forces the dialog to use a non-native quick implementation.

selectedColor : color

This property holds the currently selected color in the dialog.

The accepted () signal can be handled to get the final selection. When the user has clicked Open to accept a color, a signal handler for the accepted () signal can query the selectedColor property to get the final color that was selected by the user.
