Detailed Description

Contains functions providing a basic graphical user interface for common tasks.

The GUI support functions are declared in ic4gui/ic4gui.h.

Enumeration Type Documentation

PropertyDialogFlags

enum class PropertyDialogFlags : int

strong

Defines a set of flags to customize the behavior of the dialogs displayed by the ic4gui::showDevicePropertyDialog() and ic4gui::showPropertyDialog() functions.

Enumerator
Default	Default behavior.
AllowStreamRestart	Allows properties to be changed that require the stream to be stopped. For example, if the user changes the value of Width, the stream is stopped, the new value is set, and the stream is restarted. Programs should be careful to only specify this flag when the program is in a state where a stream restart with possible format reconfiguration is acceptable. This flag is only valid when calling ic4gui::showDevicePropertyDialog().
RestoreStateOnCancel	If set, the dialog restores all properties to their initial state when the dialog is cancelled. The User can cancel the dialog by pressing the Cancel button or closing the dialog window.
ShowTopCategory	If set, the dialog shows the top-level category in the property tree window. When the top-level category is Root, it is usually not necessary to display the name of top-level category.
HideFilter	If set, the dialog does not display the visibility dropdown and filter text box.

Function Documentation

showDeviceDialog()

bool showDeviceDialog ( ic4::WindowHandle  hParent, ic4::Grabber &  grabber, ic4::Error &  err = ic4::Error::Ignore()  )

inline

Shows a dialog that allows the user to select a video capture device.

The device is opened in the passed ic4::Grabber object.

Parameters

[in]	hParent	A parent window for the dialog
[in]	grabber	A grabber object in which the new device is to be opened
[out]	err	Reference to an error handler. See Error Handling for details.

Returns

true, if a device was selected and opened succesfully, otherwise false.

showDevicePropertyDialog()

bool showDevicePropertyDialog ( ic4::WindowHandle  hParent, ic4::Grabber &  grabber, const PropertyDialogOptions &  opt = {}, ic4::Error &  err = ic4::Error::Ignore()  )

inline

Shows a dialog box allowing the user to configure the properties of the video capture opened in the passed ic4::Grabber.

Parameters

[in]	hParent	A parent window for the dialog
[in]	grabber	A grabber object whose video capture device is to be configured
[in]	opt	An options structure to customize the dialog's behavior
[out]	err	Reference to an error handler. See Error Handling for details.

Returns

true, if the user closed the dialog using the OK button, otherwise false.

showPropertyDialog()

bool showPropertyDialog ( ic4::WindowHandle  hParent, const ic4::PropertyMap &  map, const PropertyDialogOptions &  opt = {}, ic4::Error &  err = ic4::Error::Ignore()  )

inline

Shows a dialog box allowing the user to configure the properties of a ic4::PropertyMap.

Parameters

[in]	hParent	A parent window for the dialog
[in]	map	A property map to configure
[in]	opt	An options structure to customize the dialog's behavior
[out]	err	Reference to an error handler. See Error Handling for details.

Returns

true, if the user closed the dialog using the OK button, otherwise false.

showSelectDeviceDialog()

ic4::DeviceInfo showSelectDeviceDialog ( ic4::WindowHandle  hParent, ic4::Error &  err = ic4::Error::Ignore()  )

inline

Shows a dialog that allows the user to select a video capture device.

A ic4::DeviceInfo representing the selected device is returned.

Parameters

[in]	hParent	A parent window for the dialog
[out]	err	Reference to an error handler. See Error Handling for details.

Returns

A ic4::DeviceInfo representing the selected device. If no device is selected, the object is invalid. Check the err output parameter or ic4::DeviceInfo::is_valid().
