Class Application

Namespace

Qt

Assembly

Qt.Bridge.CSharp.Api.dll

Sets app-wide metadata such as the app name, version, publisher details, and default window icon.

public static class Application

Inheritance

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.MemberwiseClone()

object.ReferenceEquals(object, object)

object.ToString()

Remarks

Qt Bridge for C# forwards these values to the native application object as soon as you assign them. In practice, set them near the start of Main, before LoadFromRootModule(string), so the UI sees them from the beginning:

static void Main(string[] args)
{
    Qt.Application.Name               = "MyApp";
    Qt.Application.Version            = "1.0";
    Qt.Application.OrganizationName   = "Acme Corp";
    Qt.Application.OrganizationDomain = "acme.com";
    Qt.Application.DisplayName        = "My Application";
    Qt.Application.SetWindowIcon("qrc:/assemblies/MyApp/icons/app.svg");

    Qml.LoadFromRootModule("Main");
    Qml.WaitForExit();
}

Properties

DisplayName

Sets the user-facing application name.

public static string DisplayName { set; }

Property Value

string

Remarks

Use this when the name shown to users should differ from Name. If not set, the Name value will be used.

Name

Sets the internal application name.

public static string Name { set; }

Property Value

string

Remarks

Use this as the stable programmatic name of your app. If not set, the executable name will be used as the default.

OrganizationDomain

Sets the publisher domain for the application.

public static string OrganizationDomain { set; }

Property Value

string

Remarks

This is mainly useful on platforms like macOS, where the domain is part of the app identity. Example: acme.com. Some platforms may ignore this value.

OrganizationName

Sets the publisher or company name for the application.

public static string OrganizationName { set; }

Property Value

string

Remarks

This helps Qt Bridge for C# provide publisher information to Qt, which uses it when choosing where app settings are stored on the current platform. A company or product owner name is usually the right value here.

Version

Sets the application version.

public static string Version { set; }

Property Value

string

Remarks

Use the same version string you would show in an About dialog or diagnostic output. Qt Bridge for C# passes it through to Qt, which can surface it in places such as version reporting and settings metadata.

Methods

SetWindowIcon(string)

Sets the default window icon from a packaged app resource.

public static void SetWindowIcon(string qrcUrl)

Parameters

qrcUrl string

The resource URL. Use the Qt resource form, for example: qrc:/assemblies/MyApp/icons/app.svg.

Remarks

Sets the default icon for all windows that do not specify their own. Provide the icon as a resource (e.g., qrc:/assemblies/MyApp/icons/app.png). PNG is recommended for broad compatibility; SVG is supported if the environment allows it.

Exceptions

ArgumentException

qrcUrl does not start with qrc:/.
