Detailed Description

Class for rendering an icon in UI.

Definition at line 26 of file icon.h.

Member Enumeration Documentation

◆ Status

enum Icon::Status

Enumerator
Ready	No icon has been set.
Loading	The icon loaded correctly.

Definition at line 156 of file icon.h.

Property Documentation

◆ active

bool Icon::active

readwrite

Whether this icon will use the QIcon::Active mode when drawing the icon, resulting in a graphical effect being applied to the icon to indicate that it is currently active.

This is typically used to indicate when an item is being hovered or pressed.

The color differences under the default KDE color palette, Breeze. Note that a dull highlight background is typically displayed behind active icons and it is recommended to add one if you are creating a custom component.

Definition at line 94 of file icon.h.

◆ color

QColor Icon::color

readwrite

The color to use when drawing this icon when isMask is enabled.

If this property is not set or is Qt::transparent, the icon will use the text or the selected text color, depending on if selected is set to true.

Definition at line 130 of file icon.h.

◆ fallback

QString Icon::fallback

readwrite

The name of a fallback icon to load from the icon theme when the source cannot be found.

The default fallback icon is "unknown".

import org.kde.kirigami 2.20 as Kirigami
 
Kirigami.Icon {
    source: "this-icon-does-not-exist"
    fallback: "view-refresh"
}

Note: This will only be loaded if source is unavailable (e.g. it doesn't exist, or network issues have prevented loading).

Definition at line 66 of file icon.h.

◆ isMask

bool Icon::isMask

readwrite

Whether this icon will be treated as a mask.

When an icon is being used as a mask, all non-transparent colors are replaced with the color provided in the Icon's color property.

See also: color

Definition at line 122 of file icon.h.

◆ paintedHeight

qreal Icon::paintedHeight

read

The height of the painted area measured in pixels.

This will be smaller than or equal to the height of the area taken up by the Item itself. This can be 0.

Since: 5.15

Definition at line 154 of file icon.h.

◆ paintedWidth

qreal Icon::paintedWidth

read

The width of the painted area measured in pixels.

This will be smaller than or equal to the width of the area taken up by the Item itself. This can be 0.

Since: 5.15

Definition at line 146 of file icon.h.

◆ placeholder

QString Icon::placeholder

readwrite

The name of an icon from the icon theme to show while the icon set in source is being loaded.

This is primarily relevant for remote sources, or those using slow- loading image providers. The default temporary icon is "image-x-icon"

Note: This will only be loaded if the source is a type which can be so long-loading that a temporary image makes sense (e.g. a remote image, or from an ImageProvider of the type QQmlImageProviderBase::ImageResponse)

Since: 5.15

Definition at line 79 of file icon.h.

◆ selected

bool Icon::selected

readwrite

Whether this icon will use the QIcon::Selected mode when drawing the icon, resulting in a graphical effect being applied to the icon to indicate that it is currently selected.

This is typically used to indicate when a list item is currently selected.

The color differences under the default KDE color palette, Breeze. Note that a blue background is typically displayed behind selected elements.

Definition at line 113 of file icon.h.

◆ source

QVariant Icon::source

readwrite

The source of this icon.

An Icon can pull from:

The icon theme:
import org.kde.kirigami 2.20 as Kirigami

Kirigami.Icon {

source: "view-refresh"

}
The filesystem:
import org.kde.kirigami 2.20 as Kirigami

Kirigami.Icon {

source: "/home/example/cool.svg"

}
Remote URIs:
import org.kde.kirigami 2.20 as Kirigami

Kirigami.Icon {

source: "https://example.com/kirigami.png"

}
Custom providers:
import org.kde.kirigami 2.20 as Kirigami

Kirigami.Icon {

source: "image://provider/kirigami.svg"

}
Your application's bundled resources:
import org.kde.kirigami 2.20 as Kirigami

Kirigami.Icon {

source: "qrc:/kirigami.svg"

}

Note: See https://doc.qt.io/qt-5/qtquickcontrols2-icons.html for how to bundle icon themes in your application to refer to them by name instead of by resource URL.; Use fallback to provide a fallback theme name for icons.; Cuttlefish is a KDE application that lets you view all the icons that you can use for your application. It offers a number of useful features such as previews of their appearance across different installed themes, previews at different sizes, and more. You might find it a useful tool when deciding on which icons to use in your application.

Definition at line 56 of file icon.h.

◆ status

Icon::Status Icon::status

read

Whether the icon is correctly loaded, is asynchronously loading or there was an error.

Note that image loading will not be initiated until the item is shown, so if the Icon is not visible, it can only have Null or Loading states.

Since: 5.15

Definition at line 138 of file icon.h.

◆ valid

bool Icon::valid

read

Whether this icon's source is valid and it is being used.

Definition at line 99 of file icon.h.

The documentation for this class was generated from the following files:

Icon::fallback

QString fallback

The name of a fallback icon to load from the icon theme when the source cannot be found.

Definition: icon.h:66

Icon::source

QVariant source

The source of this icon.

Definition: icon.h:56
