Repaint command

Print this Topic Previous pageReturn to chapter overviewNext page

Macro commands may be used either in macros or by sending the commands to DPlot via dynamic data exchange (DDE). Some commands are valid only in macros (noted by Macros Only). Commands sent to DPlot via DDE must be enclosed by square brackets [     ]. Macro commands should not include the brackets.

Command parameters shown in the descriptions below are placeholders for the actual values. Command parameters are either numeric values, equations that evaluate to numbers, or character strings. Character string parameters are always bound by double quotation marks. Equations must be preceded by an equals sign (=).

The pipe symbol (|) in the command syntax indicates that a parameter is optional, and should not be included in your macro unless otherwise noted.

All indices into arrays are 1-based, e.g. Curve1=1 refers to the first curve in a plot.

A 0x prefix for numbers in the descriptions below indicates hexadecimal notation; e.g. 0x0010 = 16.

JR/Viewer indicates that the command is supported by DPlot Jr or DPlot Viewer.

JR   Viewer

Similar to ViewRedraw, but simply redraws a saved bitmap of the plot if one is available. If a bitmap is not available for this document, this command is identical to ViewRedraw. This command is primarily useful in applications that that have used SetOutputWindow to set the output destination to some area within the calling application's window rather than the default DPlot document window. For example, an application might send a Repaint command to DPlot when it receives a WM_PAINT message due to the application window being covered/uncovered.

Please note that Repaint, unlike ViewRedraw, does not redraw a plot from scratch if a bitmap of the plot is available. Rather it simply does a BitBlt with the existing bitmap. So if your application uses PostponeRedraw followed by several commands that change the data or the plot in some way, then uses Repaint, you will almost certainly not get the result you expect; changes following PostponeRedraw will not be reflected in the new plot until a ViewRedraw command is issued.
