Hi,

I am a user of Orign 7. I need to create a panel for button to do custom function on active worksheet, my problem is I don't know how to create a panel(having some check boxes or input box to request information form user) after user click a button using Orign 7. When I took a look at the Programming Guide for Orign 7, I didn't find it. Is there anybody knows how to do it? Or only OrignPro has this feature. Thanks a lot.

Tracy

Panels such as you describe are called UIM objects and you need OriginPro to create them. However, the Labtalk getnumber command opens a dialog with as many as six different inputs that can be edit boxes for entering numbers or strings, check boxes or drop-down lists.

Mike:

Thank you for your quick response. When I take a look at the getnumber command in LabTalk reference, there is a example for the use of this command:
%A = enter name;
i = 1;
j = 1;
k = 0;
%B = "line1 line2 line3"; // drop down list with three entries

getn
(X Minimum) MyVar // a variable
(my boolean) k:2s // show remaining items if k = 1 (checked)
(my list) i:B // use %B as the list items
(Color) j:@C // color list, init j = 1
(Your Name) %%A // %% to preserve %A for holding the name
(Title of this dialog); // end of getnumber

I don't understand this example and I also don't know how to call and use this routine. Could you explain a little more to me. Thanks a lot!

Until Originlab provide an Origin C version of the GetNumber function in labtalk, it is quite combersome to call this labtalk function from Origin C, but I have provided an example here. You will need to put the following code in a file called test.c and put this file inside the Origin C folder.

void dd(string str, double xmin, int i, int j, int k)
{
	LT_set_str("%A", str);
	
	LT_set_var("i",i);
	LT_set_var("j",j);
	LT_set_var("k",k);
	LT_set_var("MyVar", xmin);
	printf("On input, Xmin=%f, i=%d, j=%d, k=%d, str=%s\n", xmin, i,j,k,str);
	// can use __FILE__ to find this file name, but
	// we will just hard code it here to be a file called test.c inside
	// OriginC subfolder
	if(!LT_execute("run.section(%YOriginC\\test.c,GetNum)"))
	{
		out_str("User Cancel");
		return;
	}
	double db_i, db_j, db_k;
	LT_get_var("MyVar", &xmin);
	LT_get_var("i",&db_i); // must use double to receive value from labtalk
	LT_get_var("j",&db_j);
	LT_get_var("k",&db_k);
	char	szTemp[100];
	LT_get_str("%A", szTemp, 100);

	
	printf("On output, Xmin=%f, i=%d, j=%d, k=%d, str=%s\n", xmin, (int)db_i,(int)db_j,(int)db_k,szTemp);

}
	
// this is a trick to call LabTalk section inside a C file
#ifdef _JUNK
// section name must match run.section
[GetNum]

	%B = "line1 line2 line3"; // drop down list with three entries 

	getn 
		(X Minimum) MyVar 
		(my boolean) k:2s 
		(my list) i:B 
		(Color) j:@C 
		(Your Name) %%A 
		(Title of this dialog); 
	return 0;
#endif //_JUNK


You can then compile this and type into script window
dd "some text" 5.7 1 1 1;

Hi Tracy,

I had problems too when I just copied the script from the help file and pasted it in the script window. So I'll edit it a little and remove the comments.

The following lines just initialize the variables. Copy them to your script window, hilite all six lines and press Enter.

%A = enter name;
i = 1;
j = 1;
k = 1;
MyVar = 2;
%B = "line1 line2 line3";

The next lines launch the getnumber command...

getn
(my variable) MyVar
(my boolean) k:2s
(my list) i:B
(Color) j:@C
(Your Name) %%A
(Title of this dialog);

Once again, hilite all seven lines and press enter to launch the dialog below.



1> Whatever is in the my variable box becomes the new value of MyVar when the dialog is OK'd.
2> The value of k is determined by whether or not my boolean is checked on OK. (checked: k=1, unchecked: k=0) Also, the lines beneath are only shown when my boolean is checked.
3> my (drop-down) list contains the three tokens in the string %B. The line chosen by the user determines the new value of i. (line2 sets i=2) The actual string chosen by the user can be obtained with

%L=%[%B,#i];
%L=line2 // if i=2

4> @C is a system string variable containing the names on Origin's color pallete. The choice determines the value of j.
5> The string entered in the Your Name box is assigned to the string variable %A.

That's a rather brief summary, but I hope it will get you started.
