Control Elements. Creating User Defined Dialog Boxes
All variables, except flag_21 and flag_22, are external.
Predefined lists of values are created for the variables height,
width and width_1, and dim_mode. Note that the variable
dim_mode uses a list of a special type: each numerical symbol is
separated by “;” from the string bound to this numerical value.
How to use such a list is described below. The introduced
variables allow getting different versions of the original drawing:
modifying the part size and the size of the hole, displaying axes
and various dimensions. You can also modify the font size of the
title, or hide it altogether.
Let's consider various choices of the dialogs for this example. Let's begin with creating a simple dialog for
this model, as shown on the diagram. The respective library file is “Sample single dialog.GRB”.
The dialog being created allows modifying the part size and the size of the conic hole and showing/hiding
dimension and axes display.
Call the command “TR: Create Control”. Let’s create the dialog page:
Create Dialog Page
By default, the newly created page is assigned the
type “Controls”, with the recommended sizes set
appropriately. This page is also automatically added
and check marked in the list of pages displayed by the
command "Customize|Status" (the tab
“Preferences”), while the parameter “Marked
variable editor” is switched into the mode “Pages”.
Name the new page “Part parameters”.
Grid snapping is turned on on this page by default.
You can also turn on snapping by the absolute
coordinates:
Set absolute coordinates
When using construction lines and nodes, you can use snapping to 2D nodes:
Set relation with Node
If necessary, you can define default parameters for all newly created control elements:
Edit Control Parameters
Calling the option brings up the “Control Parameters” dialog box. The latter provides the full set of
parameters for a control element. Thus, in our example, the parameter “Editable” can be turned off for
“Combo Box”-type controls.
The variables of the model, whose values will be controlled by the dialog being created, can be divided into
several groups:
Variables that drive the part sizes (height, length, width);
