Method Detail

getCustomProperty

Object getCustomProperty()
                         throws IOException,
                                AutomationException

A property to associate data with a control.

Description

Use the CustomProperty to associate any useful data with the PageLayoutControl. This is similar to a 'Tag' property, and can be use to store strings, numbers and objects.

Available with ArcGIS Engine.

Returns:

A Variant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setCustomProperty

void setCustomProperty(Object pVal)
                       throws IOException,
                              AutomationException

A property to associate data with a control.

Product Availability

Available with ArcGIS Engine.

Parameters:

pVal - A Variant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

suppressResizeDrawing

void suppressResizeDrawing(boolean suppressResize,
                           int resizeHWnd)
                           throws IOException,
                                  AutomationException

Suppress full redraw of control during resize operations.

Description

If the PageLayoutControl contains a lot of data, redrawing this data during a resize event can be costly. To increase performance you can suppress the data redraw until the resizing is complete with the SuppressResizeDrawing method. During the resize a stretched bitmap will be drawn instead.

Passing the suppressResize value sets the IScreenDisplay::SuppressResize property on the ActiveView. Pass True to suppress normal drawing and draw a stretched bitmap when a resize event begins. During the resize the data is not refereshed and the captured image is stretched. As such, the image can appear pixelated when a small display area is resized to a large display area. Pass False to resume normal drawing when a resize event ends.

In development environments that do not trap the beginning and end of a resize event, the PageLayoutControl can 'watch' the hwnd supplied to the SuppressResizeDrawing method. When a form or container starts resizing the WM_ENTERSIZEMOVE windows messge is sent and the PageLayoutControl will set suppressResize to True. When windows sends the WM_EXITSIZEMOVE message the form or container is released from resizing and the the PageLayoutControl will set suppressResize to False. Pass the hwnd of the form or container to the SuppressResizeDrawing method when the form or container is initialized. Passing an hwnd of 0 will stop the PageLayoutControl watching the hwnd.

Parameters:

suppressResize - The suppressResize (in)

resizeHWnd - The resizeHWnd (in, optional, pass 0 if not required)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getDocumentFilename

String getDocumentFilename()
                           throws IOException,
                                  AutomationException

The filename of the last map document loaded into the control.

Description

Returns the DocumentFilename of the last document loaded into the PagelayoutControl with the LoadMxFile method. An empty string will be returned if no document is loaded.

Product Availability

Available with ArcGIS Engine.

Returns:

The pVal

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setDocumentFilename

void setDocumentFilename(String pVal)
                         throws IOException,
                                AutomationException

The filename of the last map document loaded into the control.

Product Availability

Available with ArcGIS Engine.

Parameters:

pVal - The pVal (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getObject

Object getObject()
                 throws IOException,
                        AutomationException

A property that returns the underlying control. This can be used when the control is inside a wrapper object that has been added by a development environment.

Description

In some development environments it is not possible to query interface directly on the control to other COM interfaces, beacuse the control is contained within a wrapper object. To get the real control use the Object property.

Product Availability

Available with ArcGIS Engine.

Returns:

A reference to another Automation Object (IDispatch)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getKeyIntercept

int getKeyIntercept()
                    throws IOException,
                           AutomationException

A property that specifies interception of key strokes that are normally handled by the container. When intercepted the OnKeyDown and OnKeyUp events will be called. This value can be a combined bit mask of esriKeyIntercept enum values.

Description

Returns or sets keys on the keyboard that will be intercepted by the PageLayoutControl, triggering the OnKeyDown and OnKeyUp events when pressed. These keys are often hidden from the PageLayoutControl by the development environment container. By default the KeyIntercept is set to esriKeyInterceptNone .

Many development environment containers use the up, down, left and right arrow keys to change control focus on a form. These keys can also be useful for navigating around the display. To intercept the arrow keys and the Tab key combine the enum values using a logical OR operation (esriKeyInterceptArrowKeys OR esriKeyInterceptTabKey, which is 1 OR 4 = 5).

Product Availability

Available with ArcGIS Engine.

Returns:

The pVal

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setKeyIntercept

void setKeyIntercept(int pVal)
                     throws IOException,
                            AutomationException

A property that specifies interception of key strokes that are normally handled by the container. When intercepted the OnKeyDown and OnKeyUp events will be called. This value can be a combined bit mask of esriKeyIntercept enum values.

Parameters:

pVal - The pVal (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
