Problems with GFW Classes

Former Member — Mon, 04 Jun 2007 06:35:21 GMT

I use the GFW classes to show a chart ! I works fine! When I leave the dynpro who show the chart, I call the method CALL METHOD GP_INST->IF_GRAPHIC_PROXY~FREE.

When I call this Dynpro again It dow not show the chart not again! The Problem is that the USER can edit the chart Data in the dynpro which call the dynpro who show the chart!

What can I do that the user can edit the data? When I do not call CALL METHOD GP_INST->IF_GRAPHIC_PROXY~FREE. Than the Chart do not consider the new Data in the Chart! How I can delete teh data of a Chart ??

Thanx for help??

Hi,

in addition to calling free of the graphics proxy I assume that you have to do the same with your gui container instance. This should help when calling the chart again.

I am not sure how the users should edit the data in your application. But have you already checked the report GFW_DEMO_PRES? After pushing a button to display a chart you can easily change the values within the table: the chart is refreshed accordingly! Have a look at the source code of this report.

Hope that helps

Regards, Kai

Hi,

create a graph using FM GFW_PRES_SHOW.

look at demo program GFW_DEMO_PRES1

FU GFW_PRES_SHOW

____________________________________________________

Text

GFW: Simple display of a business graphic using the GFW

Functionality

GFW = Graphical Framework

GFW_PRES_SHOW is the GFW function module for business graphics.

It can display one(!) ActiveX or JAVABean ("control") graphic and includes a fallback strategy for the platforms on which controls cannot be run. On platforms that do not support controls the graphic is started as an external program (SAPBUSG).

The graphic product used by the function module is determined by product management, which is filled by SAP and enables the customer to change the priorities of the products used.

The function module has IMPORTING and TABLES parameters and EXCEPTIONS.

Parameters

CONTAINER or PARENT (importing)

Container object in which the graphic is to be placed (PARENT must have the data type TYPE REF TO CL_GUI_CONTAINER).

TOP (importing)

Alignment/upper edge of the parent object

LEFT (importing)

Alignment/left hand edge of the parent object

HEIGHT (importing)

Height of the control

WIDTH (importing)

Width of the control

PRESENTATION_TYPE (importing)

Diagram type = type in which all data series are represented (lines, points, vertical bar, pie ...)

The presentation type is determined by the constants in type group GFW (please refer to the documentation for the parameter PRESENTATION_TYPE).

If the PRESENTATION_TYPE is GFW_PRESTYPE_PIE_CHART make sure that the texts in the table parameters ROW_LABELS/COLUMN_LABELS are 20 characters or less, otherwise the sections of the pie are displayed white.

HEADER (importing)

Header (plot area)

ORIENTATION (importing)

Specifies how the data tables are interpreted

X_AXIS_TITLE (importing)

Title/label for the X-axis

Y_AXIS_TITLE (importing)

Title/label for the Y-axis

FORMAT (importing)

Format of requested export

VALUES, COLUMN_TEXTS (changing)

Tables with the data to be displayed

ROW_LABELS, COLUMN_LABELS (changing)

Table contains headings for the unique texts for the rows/columns

Example

Program DEMO_GFW_PRES_SHOW

Notes

The constants of the GFW type pool must be used because the content of the constants may change!

If you want to display several graphics with GFW function modules simultaneously, you can use the MULT function module (here: GFWPRES_SHOW_MULT).

Requirements that go beyond the range of functions described here (in particular, forcing a specific graphic product and interaction) can be programmed directly using the GFW ABAP Objects Framework.

Regards
