In the context menu, select the item “Parameters…”.
The dialog for editing properties of the selected elements
will appear in the properties window. In this dialog, clear
the marks against all parameters except the “Level”
parameter, and assign the latter a new value: flag_3 ==
0? 0:-1. Click . The entered expression means: if the
variable flag_3 is equal to 0, then the parameter “Level”
will be assigned the value 0, otherwise - (-1).
Thus, the dialog is created, and we can call it by the
command “Parameters|Model”. Calling the command
brings up this dialog box on the screen.
When the flag “Display Title” is turned on, the
parameters “Font size:” and “Text:” are present in the
dialog. If the “Display Title” flag is off, the controls for
defining the font size and the title text string are omitted
in the dialog. Therefore, the created dialog box sample
has parametric properties. One can create various
parametric dialogs of more complex structure, using the
same principle.
Working with Multiple Dialogs
As was mentioned above, multiple dialogs can be created within one model. Let's get back to the dialog
instance with a preview pane and a picture. In addition to the existing dialog, let's create a dialog with
controls for the title of the drawing. The file of this instance is “Sample dialog with tabs.GRB”.
Call again the command “TR: Create Control”. Using the option , create a page for the second dialog.
Rename it with the help of the command “Pages”, setting the name “Drawing title”.
As it was mentioned, the variables “flag_3”, “size” and $text control the visibility, size and the contents of
the drawing title text string, respectively. For each variable's control element, let's create the three respective
“Group Box” elements, as shown on the diagram.
As before, create a “Check Box” for switching
the values of the variable flag_3.
Place this control inside the first group, as shown on
the diagram. In the window “Insert Variable”, select
the variable flag_3. In the “Control Parameters”
dialog box, assign the parameter “Caption” the string
value “Display Drawing Title”. Set the parameter
“On” to “0”, “Off” – “-1”.
We will use the “Edit Box” control for modifying the
title text, with the flag “Multiline EditBox” turned on.
We need to put the explanation text “Title Text:” before the “Edit Box”. To do this, use a “Static Text”
element.
