The top part of the pane displays properties that are common to all elements, such as element type, position, size, and visibility. The Properties pane displays all the properties of the selected QML element. The Resources pane displays the images and other files that you copy to the project folder (to the same subfolder as the QML files). The Qt Quick Application wizard adds the import statements automatically when you select the component set to use for your project. To view the UI components in the Library pane, add import statements to the. Sets of UI components with the MeeGo and Symbian look and feel have been defined for Qt Quick. The Items pane displays the QML elements grouped by type: your own QML components, basic elements, positioner elements, and views. The Library pane contains two tabs: Items and Resources. Drag and drop the element to another position in the tree or use the arrow buttons to move the element in the tree. You can change the parent of an element also in the Navigator pane. ![]() The topmost element under the cursor becomes the new parent of the element. To change the parent of the element, press down the Shift key before you drag and drop the element into a new position. Therefore, the parent element is not automatically changed. When you move elements on the canvas, Qt Quick Designer cannot determine whether you want to adjust their position or attach them to a new parent element. When you drag and drop QML elements to the canvas, Qt Quick Designer adds the new element as a child of the element beneath it. You can raise or lower the stack value of an item or move the item to the front or back of all its siblings. To change the stacking order of an item, right-click it on the canvas and select Stack (z). Elements with the same stacking value are drawn in the order they are listed, from the last item up. By default, elements with a higher stacking value are drawn on top of siblings with a lower stacking value. The z property of an element determines its position in relation to its sibling elements in the element hierarchy. To view several types of content at a time, split the sidebar by clicking. To view lists of files or projects, instead, select File System, Open Documents, or Projects in the menu. To hide or show child elements, edit the properties of the parent element. If you set Opacity to 0, elements are hidden, but you can still apply animation to them.Īs all properties, visibility and opacity are inherited from the parent element. To change the visibility of an element in the application, use the Visibility check box or the Opacity field in the Properties pane. Click the icon to change the visibility of an element on the canvas. You can show and hide items to focus on specific parts of the application. When you remove an element, the child elements are also removed. ![]() When you copy an element, all its child elements are also copied. For example, you might want to make a mouse area larger than the rectangle or image beneath it. However, they do not necessarily have to fit inside the parent element. Typically, child elements are located within the parent element on the canvas. To select elements on the canvas, right-click an element, and select another element in the context menu. Elements can access the properties of their parent element. ![]() You can select elements in the Navigator to edit their properties in the Properties pane. Elements are listed in a tree structure, below their parent. The Navigator pane displays the QML elements in the current QML file and their relationships. QML states typically describe user interface configurations, such as the UI elements, their properties and behavior and the available actions.
