Blender 2.49 GUI: How to store text inputed from a "Blender.Draw.String" Textbox

Coding Python Support
#1

Hello Everyone.

I am new to Blender GUI, & the older version is tough because there is no code_Completion on the Console which I used to learn libraries in the latest Blenders 2.5~. But my problem is that my Mentor has asked me to create a clean WIndow rather than the Panels that are under existing Windows in the so called Blender 2.5~

I have used this to create my Textboxes. I will post the whole code after this:

textInput = Blender.Draw.Create(strInput)
textInput = Blender.Draw.String("Str: ",3,100,150,100,20,textInput.val,20,“its tooltip”)
strInput = textInput.val

#This is the Code#


#!BPY

import bpy
import Blender
import activeFace as faceOperations




strInput = "Empty"

Blender.BGL.glClear(Blender.BGL.GL_COLOR_BUFFER_BIT)    

#Create the GUI Widgets
def drawMe():            #Not reserved
    Blender.BGL.glClear(Blender.BGL.GL_COLOR_BUFFER_BIT)
    # Toggle(name,event,x,y,width,height,default,"popupTooltip")
    Blender.Draw.Toggle("ClearLocation",1, 10,20, 100,20,0,"Tooltip")
    Blender.Draw.Toggle("TransLate",2,20,100, 100,20,0,"Tooltip2")
    
    
    #Create LabelBox
    Blender.Draw.Label("myLabel",10,150,100,20)
     
    #Create inputs
    global textInput,strInput
    #textInput = Blender.Draw.Create(strInput)
    intInput = Blender.Draw.Create(0)

    #Create TextBox
    print "Before",strInput
    textInput= Blender.Draw.String("Str: ",3,100,150,100,20,strInput,20,"its tooltip")
    strInput = textInput.val
    print "After",textInput,strInput
    
def event(evt,val):
    if evt == Blender.Draw.ESCKEY:
        Blender.Draw.Exit()
                return 


Blender.Draw.Register(drawMe,event)

#Problem:
My Text dissappears from the Textbox when I move the cursor away or click a button. I need to store a String from User Input
It appears as if Blender Runs the whole scripts from scratch everytime the GUI refreshes(redraws)

I tried making a global variable " strInput" to keep the String beyond the function " drawMe()"

Don’t you need to define strInput as global within the def? Otherwise python makes a local copy with the same name, which is an empty string.

def DrawMe ():
    global strInput
#5

I have done that look under:
#Create inputs

#6

I found the Solution after ‘hacking’ it::smiley: I only had to declare Blender.Draw.Create type variables at a Global Scope.



myString = Blender.Draw.Create("myText")

def draw():global myString

myString = Blender.Draw.String(""+": ",2,50,50, 300,20,\
       myString.val,20," tooltip for this widget")

I appears that Blender calls the draw() functions recursively during runtime.
