Description

window.createInput() introduced in #5107 have only the base functionality, reused from QuickOpenExtImpl:

• value (Current input value)
• placeholder (Optional placeholder in the filter text)
• password (If the input value should be hidden. Defaults to false)
• prompt (An optional prompt text providing some ask or explanation to the user)
• onDidChangeValue (An event signaling when the value has changed)
• onDidAccept (An event signaling when the user indicated acceptance of the input value)
• validationMessage (An optional validation message indicating a problem with the current input value)
• show()

Functionality that is not supported by QuickOpenExtImpl but declared in InputBox:

• buttons (Buttons for actions in the UI)
• onDidTriggerButton (An event signaling when a button was triggered)
• step / totalSteps (An optional current / total step count)
• busy (If the UI should show a progress indicator)
• enabled (If the UI should allow for user input)

Hi, I’ve already started work on both https://github.com/theia-ide/theia/issues/5107 and https://github.com/theia-ide/theia/issues/5109 as well as implementing the QuickInput API as part of https://github.com/theia-ide/theia/issues/5084. It should be done in a week or two. I just wanted to let you know so we don’t duplicate work (if you were going to work on this issue).
