    Hi, I am new to widgets. I am entering floating point numbers in my text widget, but once they have passed through event handling they are returned as integer values. Does this sound like something familiar to you that I may be missing? Thanks

    First of all, all numeric values returned to IDL through a text widget arrive as a string array datatype. That is, if you enter in a text box: 1.2345 then the commands: widget_control, wText, GET_VALUE=text help, text should reveal the following about the 'text' variable TEXT STRING = Array[1] If you subsequently have a call like: myFirstFloatEntry = float(text[0]) help, myFirstFloatEntry you should see the following datatype and value assigned to the 'myFirstFloatEntry' variable: MYFIRSTFLOATENTRY FLOAT = 1.23435 Knowing this now, can you see where your capture of your numeric entries in your WIDGET_TEXT is going wrong?
