Using Qt Bridge for Figma

Organizing Designs

To get the best results during export and import, follow these guidelines when working with Figma:

• Use pages for different purposes, such as sketching for trying out ideas, components for creating UI components, assets for images that you use in the components, and screens for building the UI screens using components and assets.
• Arrange each page into frames. When you are happy with a design, move it from the sketching page to the components page and use it in screens. When you export your assets, you can skip all frames that you don't want to be part of the final UI, to avoid cluttering the Qt Design Studio project. The code generated in Qt Design Studio corresponds to the structure of your Figma document.
• Qt Bridge for Figma supports Figma components. Each Figma component is exported as a Qt Design Studio component, and each Figma component instance is generated as a respective component instance in the component files generated when you import the design into Qt Design Studio.
• Create components with instances in Figma and export them to Qt Design Studio. Qt Design Studio friendly Figma components make it easier to create, for example, button states, connections, animations, and transitions.
• Qt Bridge for Figma does not support exporting changes in component instances. If you make changes to component instances in Figma, you must detach the instances before exporting them. Similarly, if your Figma components contain nested components, Figma allows you to hot swap the nested instance inside the component instance. However, Qt Bridge for Figma doesn't support this so you get the original component unless you detach the component instance before exporting it.
• Use descriptive and unique IDs to avoid duplicate IDs after exporting designs and importing them to Qt Design Studio.

To use the fonts that you use in Figma also in Qt Design Studio, you need to add them to Qt Design Studio as assets. Qt Design Studio deploys them to devices when you preview the UI. For more information, see Using Custom Fonts.

Items You Can Export

You can export the following parts of your design using Qt Bridge for Figma:

• Images
• Vector images
• Layers
  • Text layers
  • Shape layers
• Components
• Component instances
• Frames
• Groups

Using Frames

Frames are exported as components of the Rectangle type by default. However, if you have applied effects to the frames that Qt Bridge for Figma cannot handle, such as gradient fill colors or a mixed radius, the frames are exported as images.

Using Variables

With Qt Design Studio 4.6, variables are exported as a QML module named DesignSystem. A QML singleton is created for each collection. Modes of the collection are exported as theme objects. A collection has a currentTheme property, updating the property changes the active theme.

When a variable is bound to a property of a layer, the DesignSystem module import is added to the generated code and the property binding is created accordingly.

To export variables, select Export Variables from Settings.

Using Variants

Figma variants are exported as a component with states. All variants inside a component-set are merged together and the differences across the variants are translated into states.

For an optimal output, follow these guidelines:

• Qt Bridge for Figma panel is disabled for variants. Before adding a variant to a component, the Qt Bridge for Figma settings for the component should be complete.
• Do not change the layer names across the variants. The ID of a layer is derived from the layer name which in turn is used to identify the property differences for the state generation, so it is essential to keep the layer names same across variants.
• Adding and removing layers across the variants is fine and encouraged to create the variant differences.

Exporting Designs

To export your design using Qt Bridge for Figma:

1. Specify settings for exporting each group and layer.
2. Select Export to export your design.
3. When the exporting is done, select OK.

Qt Bridge for Figma exports everything into a .qtbridge archive. You can import the archive into a project in Qt Design Studio, as described in Importing 2D Assets.

Export Settings

You can specify export settings in the Home tab and in the Settings tab.

Home

You can specify settings for exporting each group and layer.

property int counter: 5
property string label: "ok"
antialiasing : true
width: parent.width / 2

- width

Connections {
    target: myItem
    onVisibleChanged: console.log(original_Text.visible)
}

Settings

You can export assets in the selected format (JPG, PNG, or SVG).

By default, vectors are exported as SVG Path Item components from the Qt Quick Studio Components module. This might not work for layers that have particular effects applied to them. In that case, the layers are exported as images.

Because MCUs only support simple images, disable the Export as shapes check box when designing for MCUs.
