DtOsgSensorViewDateTimeOverlaySection provides a sensor view overlay that displays the current date and time in a specified location. This information is useful for situational awareness, data logging, and mission planning. The overlay is positioned in the upper right corner of the sensor view by default.

◆ ~DtOsgSensorViewDateTimeOverlaySection()
| virtual DtOsgSensorViewDateTimeOverlaySection::~DtOsgSensorViewDateTimeOverlaySection |
( |
| ) |
|
|
overridevirtual |
Destructor.
Cleans up resources used by the date/time overlay section, particularly the text display objects.
◆ DtOsgSensorViewDateTimeOverlaySection()
| DtOsgSensorViewDateTimeOverlaySection::DtOsgSensorViewDateTimeOverlaySection |
( |
makVrv::DtDe & | de | ) |
|
|
inlineprotected |
Protected constructor.
- Parameters
-
| de | Reference to the display engine |
Creates a new date/time overlay section. This constructor is protected because instances should only be created through the creator class.
References de(), and myText.
◆ initialize()
| virtual void DtOsgSensorViewDateTimeOverlaySection::initialize |
( |
makVrv::DtOverlayRenderer & | overlayRenderer, |
|
|
unsigned int | windowWidth, |
|
|
unsigned int | windowHeight, |
|
|
unsigned int | channelXOffset, |
|
|
unsigned int | channelYOffset ) |
|
overridevirtual |
Initializes the overlay section.
- Parameters
-
| overlayRenderer | Renderer for creating overlay elements |
| windowWidth | Width of the window in pixels |
| windowHeight | Height of the window in pixels |
| channelXOffset | X offset of the channel in pixels |
| channelYOffset | Y offset of the channel in pixels |
Initializes the overlay section by creating the text element that displays the date and time. This must be called prior to any update calls. The position of the text is calculated based on the window dimensions and channel offsets.
◆ setChannelSize()
| virtual void DtOsgSensorViewDateTimeOverlaySection::setChannelSize |
( |
unsigned int | windowWidth, |
|
|
unsigned int | windowHeight, |
|
|
unsigned int | channelXOffset, |
|
|
unsigned int | channelYOffset ) |
|
overridevirtual |
Updates the overlay when the channel size changes.
- Parameters
-
| windowWidth | New width of the window in pixels |
| windowHeight | New height of the window in pixels |
| channelXOffset | New X offset of the channel in pixels |
| channelYOffset | New Y offset of the channel in pixels |
Adjusts the position and size of the text element when the channel dimensions or position change. This ensures the date/time display maintains its relative position in the view.
◆ update()
| virtual void DtOsgSensorViewDateTimeOverlaySection::update |
( |
const makVrv::DtOsgObserverObject & | observer, |
|
|
const makVrv::DtSensorFieldOfViewData & | state ) |
|
overridevirtual |
Updates the date and time display.
- Parameters
-
| observer | Observer object representing the viewer's position and orientation |
| state | Current state of the sensor field of view |
Updates the overlay text with the current system date and time during each frame update. The date and time format is based on system settings.
◆ sectionName()
| virtual const std::string & DtOsgSensorViewDateTimeOverlaySection::sectionName |
( |
| ) |
const |
|
overridevirtual |
Gets the unique name of this overlay section.
- Returns
- Reference to the section name string
Returns the name of this section with which it may be retrieved from the DtOsgSensorViewOverlay. Each section type has a unique name.
◆ DtOsgSensorViewDateTimeOverlaySectionCreator
◆ TextHorizLocation
| const double DtOsgSensorViewDateTimeOverlaySection::TextHorizLocation = 0.98 |
|
private |
Horizontal position of the text as a fraction of display width (0.0-1.0)
Value of 0.98 positions the text near the right edge of the display
◆ TextVertLocation
| const double DtOsgSensorViewDateTimeOverlaySection::TextVertLocation = 0.95 |
|
private |
Vertical position of the text as a fraction of display height (0.0-1.0)
Value of 0.95 positions the text near the top edge of the display
◆ DefaultFontSize
| const double DtOsgSensorViewDateTimeOverlaySection::DefaultFontSize = 12 |
|
private |
Default font size for the date/time text in points.
◆ TextBoxWidth
| const double DtOsgSensorViewDateTimeOverlaySection::TextBoxWidth = 0.3 |
|
private |
Width of the text box as a fraction of display width.
◆ TextBoxHeight
| const double DtOsgSensorViewDateTimeOverlaySection::TextBoxHeight = 0.3 |
|
private |
Height of the text box as a fraction of display height.
◆ SectionName
| const std::string DtOsgSensorViewDateTimeOverlaySection::SectionName |
|
static |
Static constant defining the section name.
This string identifier is used to register and retrieve this overlay section.
◆ myText
| makVrv::DtTextProxy* DtOsgSensorViewDateTimeOverlaySection::myText |
|
protected |
Text element displaying the date and time.
Pointer to the text proxy object that renders the date and time text. This is created during initialization and updated during each update call.
