DialogDrawerMenuand ToolTip. Popup is the base type of popup-like user interface controls. It can be used with Window or ApplicationWindow.

In order to ensure that a popup is displayed above other items in the scene, it is recommended to use ApplicationWindow. ApplicationWindow also provides background dimming effects. Popup does not provide a layout of its own, but requires you to position its contents, for instance by creating a RowLayout or a ColumnLayout. Items declared as children of a Popup are automatically parented to the Popups's contentItem. Items created dynamically need to be explicitly parented to the contentItem.

The implicitWidth and implicitHeight of a popup are typically based on the implicit sizes of the background and the content item plus any insets and paddings. These properties determine how large the popup will be when no explicit width or height is specified. The geometry of the contentItem is determined by the padding.

The following example reserves 10px padding between the boundaries of the popup and its content:. The background item fills the entire width and height of the popup, unless insets or an explicit size have been given for it. Negative insets can be used to make the background larger than the popup.

The following example uses negative insets to place a shadow outside the popup's boundaries:. If only a single item is used within a Popup, it will resize to fit the implicit size of its contained item. This makes it particularly suitable for use together with layouts. In this case, Popup cannot calculate a sensible implicit size. Since we're anchoring the PageIndicator over the SwipeViewwe can simply set the content size to the view's implicit size:. Similar to items in Qt Quick, Popup's x and y coordinates are relative to its parent.

This means that opening a popup that is a child of a Buttonfor example, will cause the popup to be positioned relative to the button. The following example uses the attached Overlay.

Another way to center a popup in the window regardless of its parent item is to use anchors. To ensure that the popup is positioned within the bounds of the enclosing window, the margins property can be set to a non-negative value.

See also focus and Keyboard Focus in Qt Quick. A common use case is to center a popup within its parent. One way to do this is with the x and y properties. Anchors offer a more convenient approach:. It is also possible to center the popup in the window by using Overlay :.

Note: Popups can only be centered within their immediate parent or the window overlay; trying to center in other items will produce a warning. See also Popup Positioning and anchors. This property holds the height available to the contentItem after deducting vertical padding from the height of the popup.

See also paddingtopPaddingand bottomPadding. This property holds the width available to the contentItem after deducting horizontal padding from the width of the popup.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Whenever i select chkbox or txtedt from combobox drop down list, then my combo box should connect me to actual checkbox and textedit element respectively.

EDIT Here is the code and the problem i am facing with combobox options is, neither i am not able to get icons in my message dialog nor i dont know how i can see checkbox or line edit in message dialog, i am a beginner and struggling to explore the tricky ways used in QML. I still can't understand what are you going to do. Assume, you want some custom dialog with varying content.

First of all, I guess MessageDialog is not good idea just because you cannot define custom controls inside it. But you can create a custom one. Here I use Loader to load appropriate content according to popupType property 1 - combobox, 2 - textedit. Here I use Connections to get back some result from the dialog. If you don't need it just remove the Connections item.

Similarly to ApplicationWindow and PageDialog is organized into three sections: headercontentItemand footer. Dialog's title is displayed by a style-specific title bar that is assigned as a dialog header by default.

Dialog's standard buttons are managed by a DialogButtonBox that is assigned as a dialog footer by default. The dialog's standardButtons property is forwarded to the respective property of the button box. Furthermore, the accepted and rejected signals of the button box are connected to the respective signals in Dialog.

A modal dialog blocks input to other content beneath the dialog. When a modal dialog is opened, the user must finish interacting with the dialog and close it before they can access any other content in the same window. A modeless dialog is a dialog that operates independently of other content around the dialog.

When a modeless dialog is opened, the user is allowed to interact with both the dialog and the other content in the same window. This property holds the dialog footer item.

The footer item is positioned to the bottom, and resized to the width of the dialog. The default value is null.

It provides a more mature set of controls, which are not based on Qt Quick Controls 1 and are redesigned from scratch to gain a significant performance boost. Enough has already been said about the bottlenecks with Qt Quick Controls 1 and its complicated design to support a whole variety of use cases, so let's not dig into it again.

But if you are interested, refer to these blog posts:. The new version 2. The APIs provided by the new controls take a more declarative approach, for instance, using attached properties extensively. They also provide more advanced and low-level features such as inheriting font, locale, and style. Such features were supported by Qt Widgets since day one, but they never existed in Qt Quick Controls 1. The latter two are based on Google's Material and Microsoft's Universal styles, which are platform- and device-agnostic designs with publicly available specifications.

There are no native styles in Qt Quick Controls 2 - all styles are cross-platform and look the same on all platforms. Here is a preview of these styles in action:. You could style a single control in your application to give it a different look than what is offered by these styles. In fact, the new controls also enable creating complete style-sets that could be applied to all or several instances of controls used in your application.

Invariably, different platforms have their dialog buttons in different orders.

DialogButtonBox allows a developer to add buttons to it and will automatically use the appropriate order for the user's platform.

Most dialogs have buttons that can almost be considered standard e. OK and Cancel buttons. It is sometimes convenient to create these buttons in a standard way.

There are a couple ways of using DialogButtonBox. One way is to specify the standard buttons e. OKCancelSave and let the button box setup the buttons. When a button is clicked in the button box, the clicked signal is emitted for the actual button that is pressed. For convenience, if the button has an AcceptRoleRejectRoleor HelpRolethe acceptedrejectedor helpRequested signals are emitted respectively.

See also standardButtons. Note: If the button box is assigned as a header or footer of ApplicationWindow or Page, the appropriate position is set automatically. See also Dialog::header and Dialog::footer. See also standardButton. This attached property holds the button box that manages this button, or null if the button is not in a button box. This signal is emitted when a button defined with the AcceptRole or YesRole is clicked.

In this way you can control the window's properties, appearance and layout from QML. ApplicationWindow supports popups via its overlay property, which ensures that popups are displayed above other content and that the background is dimmed when a modal or dimmed popup is visible.

Note: By default, an ApplicationWindow is not visible. Even though this approach is fine for many applications and use cases, for a generic QML component it may not be acceptable as it creates a dependency to the surrounding environment. ApplicationWindow provides a set of attached properties that can be used to access the window and its building blocks from places where no direct access to the window is available, without creating a dependency to a certain window id.

A QML component that uses the ApplicationWindow attached properties works in any window regardless of its id. The following example uses the attached overlay property to position the popup to the center of the window, despite the position of the button that opens the popup.

This property holds the control that currently has active focus, or null if there is no control with active focus.

QML Qt 146 - Dialogs and Text Fields

The difference between Window::activeFocusItem and ApplicationWindow::activeFocusControl is that the former may point to a building block of a control, whereas the latter points to the enclosing control.

See also Window::activeFocusItem. The background item is stacked under the content itembut above the background color of the window. The background item is useful for images and gradients, for example, but the color property is preferable for solid colors, as it doesn't need to create an item.

Note: If the background item has no explicit size specified, it automatically follows the control's size. In most cases, there is no need to specify width or height for a background item.

See also Customizing ApplicationWindowcontentItemheaderfooterand overlay. The data property allows you to freely mix visual children, resources and other windows in an ApplicationWindow. If you assign an Item to the contentData list, it becomes a child of the window's contentItemso that it appears inside the window. The item's parent will be the window's contentItem.

It should not generally be necessary to refer to the contentData property, as it is the default property for ApplicationWindow and thus all child items are automatically assigned to this property. See also contentItem. The content item is stacked above the background item, and under the headerfooterand overlay items.

See also backgroundheaderfooterand overlay. The default font depends on the system environment. Finally, the font is matched against Qt's font database to find the best match. ApplicationWindow propagates explicit font properties to child controls.

If you change a specific property on the window's font, that property propagates to all child controls in the window, overriding any system defaults for that property.

This property holds the window footer item. The footer item is positioned to the bottom, and resized to the width of the window. The default value is null. See also header and Page::footer.

This property holds the window header item. The header item is positioned to the top, and resized to the width of the window. See also footer and Page::header. The default locale depends on the system environment. ApplicationWindow propagates the locale to child controls. If you change the window's locale, that locale propagates to all child controls in the window, overriding the system default locale.
