Blender - Inserting a text button using bpy - user-interface

Question

I'm designing a simple GUI for a Blender 2.80 plug-in. I've created a dialog box to enter some data:
I would like to replace the line of text ("Lorem ipsum ...") with a button with a custom label (example "click here to visit our website").
Below is the code I am using:
class ExportFDSCloudHPC(Operator):
bl_idname = "..."
bl_label = "Title"
bl_description = "..."
data1 = bpy.props.StringProperty(
name = "Text 1",
default = "..."
)
data2 = bpy.props.StringProperty(
name = "Text 2",
default = "..."
)
data3 = bpy.props.StringProperty(
name = "Text 3",
default = "..."
)
def draw(self, context):
col = self.layout.column(align = True)
col.prop(self, "data1")
self.layout.label(text="Lorem ipsum dolor sit amet, consectetur adipisci elit...")
col = self.layout.column(align = True)
col.prop(self, "data2")
col = self.layout.column(align = True)
col.prop(self, "data3")
def execute(self, context):
...

To get button you need to provide an existing operator: row.operator("wm.save_as_mainfile") button text is defined in operator. If you want to change name of existing operator use row.operator("wm.save_as_mainfile", text='My Save Label')
You can create own operator:
import bpy
def main(context):
for ob in context.scene.objects:
print(ob)
class SimpleOperator(bpy.types.Operator):
"""Tooltip"""
bl_idname = "object.simple_operator" # <- put this string in layout.operator()
bl_label = "Simple Object Operator" # <- button name
#classmethod
def poll(cls, context):
return context.active_object is not None
def execute(self, context):
main(context)
return {'FINISHED'}
def register():
bpy.utils.register_class(SimpleOperator)
def unregister():
bpy.utils.unregister_class(SimpleOperator)
if __name__ == "__main__":
register()
# test call
bpy.ops.object.simple_operator()
and then use it like that:
[..]
col.prop(self, "data1")
col.operator("object.simple_operator")
# self.layout.label(text="Lorem ipsum dolor sit amet, consectetur adipisci elit...")
col = self.layout.column(align = True)
[..]
