Member Function Documentation

◆ AddLayer()

void tmLayerManager::AddLayer ( wxCommandEvent & event )

Response to the event sent by the "Add Gis Data" menu.

This function is doing following operations :

Checking that #tmTOCCtrl is ready : tmTOCCtrl::IsTOCReady()
Importing data
Saving layer to the database and getting back his real ID
Adding layer to the tmTOCCtrl with his real ID.

◆ GroupAdd()

void tmLayerManager::GroupAdd ( wxCommandEvent & event )

Create the group, and add it to the database. Then call the TocCtrl and add it.

◆ InitLayerManager()

bool tmLayerManager::InitLayerManager ( DataBaseTM * db )

Init the layer manager with a project.

Call this function when a project is opened, this allows the needed initialization to takes place.

Parameters

db	Pointer to a valid DataBaseTM object (ASSERT is done in debug mode)

Returns: Always TRUE for the moment

Date: 07 July 2008

◆ LoadProjectLayers()

bool tmLayerManager::LoadProjectLayers ( )

Load all layers (non threaded)

This functions does closely the same that the ReloadProjectLayers() one but isn't threaded and is called during project opening.

Author: Lucien Schreiber (c) CREALP 2008

Date: 24 July 2008

◆ OnDisplayProperties()

void tmLayerManager::OnDisplayProperties ( wxCommandEvent & event )

Show properties dialog.

Parameters

event Contain the tmLayerProperties info. Use GetClientInfo() for getting info out.

Author: Lucien Schreiber (c) CREALP 2008

Date: 22 October 2008

◆ OnScaleChanged()

void tmLayerManager::OnScaleChanged ( wxCommandEvent & event )

Called when user change scale.

This function is called by the Scale control (tmScaleCtrlCombo) when user specify a scale.

Parameters

event empty.

Author: Lucien Schreiber (c) CREALP 2008

Date: 14 October 2008

◆ OnShowLayer()

void tmLayerManager::OnShowLayer ( wxCommandEvent & event )

Called when showing or hiding a layer.

This function is called by the TOC (#tmTOCCtrl) when a layers is displayed or hidden

Parameters

event empty.

Author: Lucien Schreiber (c) CREALP 2008

Date: 14 October 2008

◆ OnSizeChange()

void tmLayerManager::OnSizeChange ( wxCommandEvent & event )

Called when windows size change.

This function is called by the renderer (tmRenderer) when the size change. It call the rendering of all layers in a multi-threaded way.

Parameters

event

Contain a tmArraySize with :

Item 0 containing the old Size (in pixels).
Item 1 containing the new size (in pixels).

◆ OnUpdateCoordinates()

void tmLayerManager::OnUpdateCoordinates ( wxCommandEvent & event )

Respond to mouse mouve inside renderer area.

This function is called automatically by the tmRenderer class when the mouse is moved inside the display area

Author: Lucien Schreiber (c) CREALP 2008

Date: 24 July 2008

◆ OnZoomToFit()

void tmLayerManager::OnZoomToFit ( )

Called when user press Zoom to fit.

This functions does the following :

Loading all visible layers (computing maximum extent)
Drawing This function is threaded, one can call this multiple time, if a thread allready exists it will be destroyed and a new one will be started

◆ RemoveLayer()

void tmLayerManager::RemoveLayer ( wxCommandEvent & event )

Response to the event sent by the #tmTOCCtrl.

Item was already deleted from the tmTOCCtrl and is now removed from the DB and the display is refreshed.

Parameters

event Contain the layer database ID into the GetExtraLong() function

Author: Lucien Schreiber (c) CREALP 2008

Date: 11 July 2008

◆ SelectedClear()

bool tmLayerManager::SelectedClear ( )

Clear all selected objects.

This function clear all selected objects

Returns: true if they where selected items, false otherwise

Author: Lucien Schreiber (c) CREALP 2009

Date: 31 March 2009

◆ SelectedInvert()

bool tmLayerManager::SelectedInvert ( )

Invert selected values.

Returns: true if sucess, false otherwise

Author: Lucien Schreiber (c) CREALP 2009

Date: 31 March 2009

◆ SelectedSearch()

bool tmLayerManager::SelectedSearch	(	const wxRect &	rect,
		bool	shiftdown = `false`
	)

Searching data for selection.

This function search and update the tmSelectedDataMemory structure with searched data. If this function return true we should redraw all layers

Parameters

rect	area we sould search for selecting data
shiftdown	status of the shift key. If down we mainly add data to the selection

Returns: true if function succeed and we should reload layers, false otherwise

Author: Lucien Schreiber (c) CREALP 2008
