suppressResizeDrawing

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

Suppress full redraw of control during resize operations.

Description

If the MapControl 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 MapControl 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 MapControl will set suppressResize to True. When windows sends the WM_EXITSIZEMOVE message the form or container is released from resizing and the the MapControl 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 MapControl watching the hwnd.

getObject

public Object getObject()
                 throws IOException,

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.

Specified by:

getObject in interface IMapControl3

Returns:

A reference to another Automation Object (IDispatch)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

Indicates if map tips are shown.

Product Availability

Available with ArcGIS Engine.

Specified by:

setShowMapTips in interface IMapControl3

Parameters:

show - The show (in)

Throws:

IOException - If there are interop problems.

isShowMapTips

public boolean isShowMapTips()
                      throws IOException,
                             AutomationException

Indicates if map tips are shown.

Description

Determines whether map tips are displayed (if they exist) as the mouse moves over layer features. By default the ShowMapTips property is set to false. To alter the appearance and behaviour of the map tips use the TipStyle and TipDelay properties.

The text for the map tip is taken from the IActiveView::TipText property that examines the data layers to find a layer that can return map tips. Map tips are typically a field value, like a features name. For performace reasons ensure that layers that return map tips have a spatial index.

getKeyIntercept

public int getKeyIntercept()

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 MapControl, triggering the OnKeyDown and OnKeyUp events when pressed. These keys are often hidden from the MapControl 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).
