TextBoxCommandInput bottom border not rendered for numRows > 4

[william-c-anderson]

The bottom border line of a TextBoxCommandInput is not rendered if the number of lines displayed is greater than 4. I've looked but I've found no policy or documentation for this behavior. Is there some way to get the code to draw the lower border?

Hi @william-c-anderson .

The state could not be reproduced.
Is there a simple sample code?

I'm happy to supply you with a test case, @kandennti-san. Here is a little script adapted from the API sampler which shows the problem. Type a new number into the text box to reset numRows.

Thank you @william-c-anderson .

This phenomenon seems to occur when the last of CommandInputs is TextBoxCommandInput.
If something else exists below, the line below is also displayed.
Added ImageCommandInput to display 1 pixel image for trial.

class MyCommandCreatedHandler(adsk.core.CommandCreatedEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args):
        try:
・・・
            # Create an editable textbox input.
            myBox = inputs.addTextBoxCommandInput('writable_textBox', 'myTextBox', '5', 5, False)
            myBox.isFullWidth = False

            inputs.addImageCommandInput('dmy', '', "resources/dmy.png")
        except:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

It can do its job, but it also wastes space.
There seems to be no other way but to make TextBoxCommandInput not at the end.

Thanks, @kandennti , for the fast reply. Should this be filed as a (presumably low priority) defect?

[kandennti]

To be honest, I don't care if it's this bug ...
