Detailed Description
The DB Graph Signal Selector widget lists available signals (columns) from the database.
To use it set the databaseUrl property to the same value as for DatabaseGraphWidget. The signalSelectionChanged signal should be connected to suitable slot of DatabaseGraphWidget.

Property Documentation
buttonMinSize : QSize
Access functions:
| QSize | buttonMinSize() const |
| void | setButtonMinSize(const QSize &size) |
buttonSvgFile : QString
This property holds the path to the svg file that styles the widget buttons.
The path can be either to a resource or a file on disk. Note that resources can be overridden by files on disk with identical names.
Access functions:
| QString | buttonSvgFile() |
| void | setButtonSvgFile(const QString &svg) |
cdpLoggerRouting : QString
This property holds routing to CDP Logger component to connect. Will override connection string set in databaseUrl.
Access functions:
| QString | cdpLoggerRouting() |
| void | setCdpLoggerRouting(const QString &routing) |
See also databaseUrl.
closingEnabled : bool
This property holds whether the widget will be closed after selecting the database columns to display.
This option is usually set to false when using this widget directly on a form with DatabaseGraphWidget to prevent it from disappearing after selecting the columns to display. Usually set to true when this widget is opened in a new window.
Access functions:
| bool | closingEnabled() const |
| void | setClosingEnabled(bool enabled) |
See also DatabaseGraphConfigurationWidget.
contentType : CDP::GraphWidgets::SignalContent::Type
This property specifies whether to display signal name or full path (when both are available).
Access functions:
| SignalContent::Type | contentType() const |
| void | setContentType(SignalContent::Type type) |
databaseUrl : QUrl
This property holds connection string to the database.
Examples:
| Target | Connection string |
|---|---|
| CDP Logger built-in server | ip://127.0.0.1:17000 |
| CDPCompactDatastore file | file:///directory-path/log.db |
| SQLite database file | file:///directory-path/database-file.db |
Note: Consider using cdpLoggerRouting instead of hardcoded string when connecting to CDP Logger built-in server.
Access functions:
| const QUrl & | databaseUrl() const |
| void | setDatabaseUrl(const QUrl &url) |
See also cdpLoggerRouting.
fontSize : int
Access functions:
| int | fontSize() const |
| void | setFontSize(int size) |
itemSize : QSize
This property holds the size of one item in the list of available columns.
For example this could be used to increase the height of each item in list to make it easier to use on a touchscreen.
Access functions:
| const QSize & | itemSize() const |
| void | setItemSize(const QSize &size) |
virtualKeyboard : bool
This property holds whether or not to open a key pad when the filter is pressed.
Access functions:
| bool | virtualKeyboard() const |
| void | setVirtualKeyboard(bool enabled) |
