A minimalistic Python wrapper for Houdini native UI script

huilib (Houdini UI Library)

Python library for building native houdini user interfaces.

This library is a simple Python wrapper around the Houdini .ui scripting language. Although it doesn't cover even a half of all the available houdini UI controlls, it does provide most usefull of them, such as buttons, textFields, checkboxes, menus, etc. The coding style is very similar to PyQt.

It was written for fun. I hope someone finds it usefull.

See examples/all_gadgets.py

Simple Import Dialog

from huilib import *

class SimpleImportDialog(HDialog):
    def __init__(self, name, title):
        super(SimpleImportDialog, self).__init__(name, title)
        self.setWindowLayout('vertical')

        # Column Layout
        col = HColumnLayout()
        self.filefield = HFileField('geo_field', 'Geo:', type_filter = 'geo')

        # Buttons in row Layout
        self.importButton = HButton('import', 'Import')
        self.closeButton = HButton('close', 'Close')
        row = HRowLayout()
        row.addGadget(self.importButton)
        row.addGadget(self.closeButton)

        # Add file field and buttons raw layout
        col.addGadget(self.filefield)
        col.addLayout(row)

        # Connect button signals
        self.closeButton.connect(self.close)
        self.importButton.connect(self.cb_import)
        self.addLayout(col)

        # This method should ALWAYS be called last!
        self.initUI()


    def cb_import(self):
        val = self.filefield.getValue()
        if not val:
            return
        geo = hou.node('/obj').createNode('geo')
        geo.node('file1').parm('file').set(val)


if __name__ == '__main__':
    ui = SimpleImportDialog(name = 'import_dlg', title = 'Import Dialog')
    ui.show()
    

huilib's Issues

Does it work with H19.5 in python 3.9?

Default Value of HCheckBox

I noticed HCheckBox's value is set to nothing at all despite being the state unticked - so it requires ticking and unticking to finally yield 0 when calling isChecked(). Note unticked corresponds with 0, and ticked corresponds with 1.

I assume this behavior isn't intended? I can attest that it's most definitely is helpful to have it set to 0 from the get go (and no doubt goes along with coding principles).

A quick and dirty fix is this if you want to add that:

To avoid meddling with the library, i'm currently doing it myself in my code, i.e.:

Anyway, thank you heaps for making this library!
