Create Dialog Box in Blender using C or Python

Question

How to make a dialog box (three options like quit/OK/Cancel) in blender and processing the text entered through python or in C. I'm unable to find any good tutorial on this. Any help....?

Answer 1

blender doesn't offer things like dialogs.

Answer 2

class DialogOperator(bpy.types.Operator)
    bl_idname = "object.dialog_operator"
    bl_label = "Save Before You QUIT!"

    def execute(self, context):
        message = " You didn't saved yet "
        self.report({'INFO'}, message)
        print(message)
        return {'FINISHED'}
    def invoke(self, context, event):
        return context.window_manager.invoke_props_dialog(self)

class DialogPanel(bpy.types.Panel)
    bl_label = "Dialog"
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"

    def draw(self, context):
        self.layout.operator("object.dialog_operator")

But this is only for creating a dialog window. after this have to insert buttons in this code.If anyone known this try to post the answer. At the same time I'm also trying to sort out this.

A quick and dirty way is to use zenity command (should be included by default in any python distribution). Try this short example script, it works in my Blender 2.69 on Ubuntu 14.04.

import bpy # bpy or bge does not matter 
import subprocess as SP
# call an OS subprocess $ zenity --entry --text "some text"
# (this will ask OS to open a window with the dialog)
res=SP.Popen(['zenity','--entry','--text',
'please write some text'], stdout=SP.PIPE)
# get the user input string back
usertext=str(res.communicate()[0][:-1])
# adjust user input string 
text=usertext[2:-1]
print("I got this text from the user: %s"%text)

See the zenity --help for more complex dialogs
