First, create the construction your tool should be able to
create later on. In the Tools menu, click on Create New Tool in order to open the corresponding dialog box. Now
you need to fill in the three tabs Output
Objects, Input Objects, and Name and Icon in order to create your
custom tool.
Example:
Create a Square-tool that creates a square whenever you
click on two existing points or on two empty spots in the Graphics View.
·
Construct a square starting with two points A
and B. Construct the other vertices and connect them with the tool Polygon to get the
square poly1.
·
Select Create New Tool in the Tools menu.
· Specify the Output Objects: Click on the square or select it from the drop down menu. Also, specify the edges of the square as Output Objects.
· Specify the Input Objects: GeoGebra automatically specifies the Input Objects for you (here: points A and B). You can also modify the selection of input objects using the drop down menu or by clicking on them in your construction.
·
Specify the Tool
Name and Command Name for your
new tool.
Note: The Tool
Name will appear in GeoGebra’s Toolbar,
while the Command Name can be used in
GeoGebra’s Input Bar.
· You may also enter text to be shown in the Toolbar Help.
· You can also choose an image from you computer for the Toolbar icon. GeoGebra resizes your image automatically to fit on a Toolbar button.
