\title Editing 2D Content
You design applications in the \uicontrol {Form Editor} by placing items
into it.
\image qmldesigner-form-editor.png "Form Editor view"
\section1 Resizing Items
When you select items in the \uicontrol {Form Editor}, selection handles
appear around their edges and in their corners. You can drag the selection
handles to resize items.
\if defined(qtdesignstudio)
To have the resizing done from the center of the selected item instead from
its edges, press \key Alt.
To preserve the image aspect ratio while resizing when using the corner
handles, press \key Shift. This also works on items that are anchored
using left, right, top, or bottom anchors.
To both resize from the center of the item and preserve the aspect ratio,
press \key Alt+Shift.
\endif
\section1 Snapping to Parent and Sibling Items
When you are working on a design, you can use snapping to align
items in the \uicontrol {Form Editor}. Click the \inlineimage snapping.png
button to have the items snap to their parent or sibling items. Snapping
lines automatically appear to help you position the items.
Click the \inlineimage snapping_and_anchoring.png
button to anchor the item to the items that you snap to.
Choose \uicontrol Tools > \uicontrol Options > \uicontrol {Qt Quick} >
\uicontrol {\QMLD} to specify settings for snapping. In the
\uicontrol {Parent item padding} field, specify the
distance in pixels between the parent item and the snapping lines. In the
\uicontrol {Sibling item spacing} field, specify the distance in pixels between
sibling items and the snapping lines.
The following image shows the snapping lines (1) when
\uicontrol {Parent item padding} is set to 5 pixels.
\image qmldesigner-snap-margins.png "Snapping lines on canvas"
\section1 Hiding Item Boundaries
The \uicontrol {Form Editor} displays the boundaries of items.
To hide them, select the \inlineimage boundingrect.png
button.
\section1 Previewing Component Size
The width and height of the root item in a QML file determine the size of
the component. You can reuse components, such as buttons, in different
sizes in other QML files and design UIs for use with different device
profiles, screen resolution, or screen orientation. The component size
might also be zero (0,0) if its final size is determined by property
bindings.
To experiment with different component sizes, enter values in the
\uicontrol {Override Width} and \uicontrol {Override Height} fields (1) on
the canvas toolbar. The changes are displayed in the \uicontrol {Form Editor}
(2) and in the \uicontrol States view (3), but the property
values are not changed permanently in the QML file. You can permanently
change the property values in the \uicontrol Properties view (4).
\image qmldesigner-preview-size.png "Canvas width and height"
To set the initial size of the root item, select \uicontrol Tools >
\uicontrol Options > \uicontrol {Qt Quick} > \uicontrol {\QMLD} and
specify the item width and height in the \uicontrol {Root Item Init Size}
group.
\section1 Specifying Canvas Size
To change the canvas size, select \uicontrol Tools > \uicontrol Options >
\uicontrol {Qt Quick} > \uicontrol {\QMLD} and
specify the canvas width and height in the \uicontrol Canvas group.
\section1 Refreshing the Form Editor Contents
When you open QML files in the Design mode, the items in the file are drawn
in the \uicontrol {Form Editor}. When you edit the item properties, the QML
file and the contents of the editor might get out of sync. For example, when
you change the position of an item within a column or a row, the new
position might not be displayed correctly in the \uicontrol {Form Editor}.
To refresh the contents of the \uicontrol {Form Editor}, press \key R or
select the \inlineimage reset.png
(\uicontrol {Reset View}) button.
