Constructor Detail

PjImportModel

public PjImportModel()

Constructor with default full info panel.

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Load geometry file if file name has been specified. Otherwise do nothing.

Overrides:

start in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

getBaseDir

public java.lang.String getBaseDir()

setBase

public void setBase(java.lang.String baseDir)

getCategory

public java.lang.String getCategory()

setCategory

public void setCategory(java.lang.String category)

getFileName

public java.lang.String getFileName()

setFileName

public void setFileName(java.lang.String fullFileName)

setTypeOfInfoPanel

public void setTypeOfInfoPanel(int infoType)

Set type of info panel. Method must be called before info panel has been created.

Parameters:

infoType - type of info panel, e.g. PjImportModel.FULL_INFO_PANEL

getInfoPanel

public PsPanel getInfoPanel()

Overwrite method of PsObject to allow choice of different info panels.

Overrides:

getInfoPanel in class PsObject

getConfirm

public int getConfirm()

Allow world to check whether user has choosen OK or Cancel, when existing the import dialog. For example, used by other projects to restore backupped geometry if user cancels dialog.

setConfirm

protected void setConfirm(int choice)

Set user confirmation state of import dialog, i.e. whether user has pressed OK or CANCEL or clicked in list. This allows to query this project after user interaction about the result. For example, it allows to backup the current geometry, and restore it when user cancels dialog.

setParentProject

public void setParentProject(PjProject project)

Register parent project to which the model will be loaded. When parent project is registered then a model container will be immediately added to parent project. If user selects a model from file then container model is filled or replaced if model in file has different type.

If user cancels the loading process then the container model is removed from parent project. If user accepts the loaded model then it is selected in the parent project.

load

public boolean load(java.lang.String fullFileName)

Load geometry model from file or URL and add it as selected geometry to this project.

Use getGeometry() to get a reference to the loaded model. Use getConfirm() to check whether user has accepted or cancelled an interactive loading process.

Parameters:

fullFileName - fully specified file name including code base, or URL.

Returns:

true if model has been successfully loaded.
