There are plenty of different UI elements in MT. Here, we'll be covering the interactive ones and how they behave.

Buttons

A button from the general editor buttons window.
Pressed.

The simplest of them all!

Left-clicking activates the action associated with the button. Right-clicking shows the button as clicked, but doesn't actually "click" it.

Checkboxes

Toggles a certain behaviour on or off. When on, there is a check inside the box.

These are commonly found in the instrument editor and settings.

Listviews

A listview of resolutions MT supports.

Allows selection of an element from a list, either by double left-clicking or right-clicking on the element in the list.

Listviews have a scrollbar, which behavges an audio signal by es similarly to sliders, except for the fact they are vertical, and their fine tune buttons have the arrow characters, instead of the + and -.

The most important listviews in MT are in the disk operations window and the instrument and sample menus.

Radio buttons

Radio buttons for the scale multiplier of the MT resolutions.

Select one of the given options. The selected option will have a point in the circle next to the radio button, while the rest have empty circles next to them.

You can find radio buttons in the instrument and sample editors.

Scrollbars

Horizonal.
Vertical.

Allows scrolling.

The arrow characters at the edges of the scrollbar are used for fine-tuned scrolling.

Horizonal scrollbars are seen in the pattern editor and sample editor. The vertical ones are seen in the instrument and sample menus.

Sliders

Allows setting a value from a fixed interval, by sliding the box within the slider.

The + and - buttons that are on the edge of the slider allow for a fine tune of the value which is being set, by increasing and decreasing it, respectfully.

They are commonly seen in the instrument editor (volume, panning, fine tune, fadeout, etc).

Text input fields

There are only a few of these fields in MT. They are:

The song title text input field
Instrument name text input fields
Sample name text input fields

These elements work in the following way:

Double left-clicking or right-clicking on the field toggles a cursor and allows the user to edit the text in the field
Hitting Enter saves the text into the field
Hitting Esc resets the text to what it was before the editing

Number input fields

This elements works similarly to the text input fields, with the following exceptions:

If the user inserts a non-number character before a number character, the value in the field will be set to the default one
If the user inserts a non-number character after the number and hits Enter, everything after the first non-number character is lost
