◆ DoEvents()

void PvWnd::DoEvents ( )
static

Processes all pending events for the calling thread.

If a modeless dialog is shown, it is up to the application to pump events to it. This must be called from the same thread that called ShowModeless in order to ensure that the events are processed properly by that dialog.

◆ GetPosition()

void PvWnd::GetPosition ( int32_t &  aPosX,
int32_t &  aPosY,
int32_t &  aSizeX,
int32_t &  aSizeY 
)

Get the window's position and size.

To use this method, see SetPosition.

Parameters
[out]aPosXSee SetPosition.
[out]aPosYSee SetPosition.
[out]aSizeXSee SetPosition.
[out]aSizeYSee SetPosition.

◆ GetQWidget()

QWidget * PvWnd::GetQWidget ( )

Get the display controller's (PvWnd object) handle.

Returns
The display controller's handle.

◆ SetPosition()

void PvWnd::SetPosition ( int32_t  aPosX,
int32_t  aPosY,
int32_t  aSizeX,
int32_t  aSizeY 
)

Set the window's position and size.

For standalone windows, the SetPosition method sets the window's absolute position (and size) on the desktop, where (0,0) is the top left corner of the desktop.

For embedded windows, the SetPosition method sets the embedded window's position relative to the window in which it is embedded, where (0,0) is the top left corner of the window.

Coordinates of the window's top left corner: (aPosX, aPosY)

Coordinates of the window's bottom right corner: (aPosX+aSizeX, aPosY+aSizeY)

To get the window's current position and size, use GetPosition.

Parameters
[in]aPosXThe window's position - left edge.
[in]aPosYThe window's position - top edge.
[in]aSizeXThe window's size - width.
[in]aSizeYThe window's size - height.
