Timeline

Mis à jour il y a 1 mois

    Introduction

    La timeline a été développée dans le cadre du Google Summer of Code 2017, et incluse pour la première fois dans MuseScore 3.0.

    Présentation globale

    La timeline est un outil de navigation qui propose une vue schématique de la partition où les mesures et les instruments sont ordonnés. La timeline se présente en quatre partie :

    Metaétiquettes

    Les métaétiquettes constituent le coin supérieur gauche de la timeline. Chacune contient le nom d'une métadonnée et à chacune correspond une métaligne .

    Etiquettes des instruments

    Elles constituent le coin inférieure gauche de la timeline. A chacune correspond une ligne de la grille principale.

    Métalignes

    Elles constituent la partie supérieure droite de la timeline. Chacune montre l'évolution d'un type de métaéléments.

    Grille principale

    Elle constitue la partie inférieure droite de la timeline. Elle est divisée en plusieurs "cellules" (chaque mesure de chaque portée étant représentée par une case)

    Métaéléments

    Les métaéléments sont les éléments de la partition qui ne sont pas des notes, mais qui ont leur importance (clef, indication de mesure, tempo, rehearsal marks, bar lines, and jumps and markers).

    Actions de bases

    Selectionner une mesure

    To select a measure in the timeline, press the mouse button on the cell. A blue box will appear around the selected cell and the respective measure in the score will be selected. The score view will place the selected measure in view.

    Selectionner plusieurs mesures

    Etendre la sélection

    Holding Shift and holding the left mouse button and dragging the mouse over the main grid will create a selection box. Upon releasing the mouse button, all the cells underneath the selection box will be selected, as well as all the measures in the score.

    sélectioner avec [Maj]

    If a cell is already selected, holding Shift and selecting another cell in the timeline will stretch the selection to that new cell, similar to how the score does

    sélectioner avec [Ctrl]

    If no cells are currently selected, holding Ctrl and selecting a cell will select the entire measure

    Effacer la sélection

    To clear selection, holding Ctrl and clicking anywhere on the grid or the meta rows will clear any current selection.

    Sélectionner des métavaleurs

    Selecting the meta values on the timeline will attempt to select the respective meta values in the score.

    Navigation standard

    Scrolling the mouse wheel up or down will move the grid and instrument labels down or up respectively. The meta labels and rows do not move.

    Navigation [Shift]

    Holding Shift and scrolling the mouse wheel up or down will move the grid and meta rows left or right respectively. The meta labels and instrument labels do not move.

    Naviguer avec [Alt]

    Holding Alt and scrolling the mouse wheel up or down will move the grid and meta rows left or right respectively, faster than Shift scrolling. The meta labels and instrument labels do not move.

    Dragging

    To drag the contents of the timeline, hold the left mouse button and move it around.

    Action sur les étiquettes

    Réorganiser les métaétiquettes

    All meta labels besides the measures meta may be rearranged in any way. By moving the mouse cursor onto one of the meta labels, small up and down arrows will appear. Click the left mouse button on the up arrow to swap the meta label with the one above it. Click the left mouse button on the down arrow to swap the meta label with the one below it.

    Enlever les métaétiquettes

    In order to hide all the meta labels while keeping all the meta information on the timeline, there is an arrow that appears on the measures meta when the mouse is over it. Click the left mouse button on the large up arrow to collapse all the currently visible meta rows into one row, where the meta values are staggered in that row. Click the left mouse button on the large down arrow to expand the meta rows again.

    Masquer les instruments

    All instruments--hidden or not--will be displayed on the timeline. To start this interaction, the mouse cursor is moved over an instrument label. A small eye will appear on the right side of the label that is open if the instrument is visible on the score, and closed if the instrument is hidden. Click the left mouse button on the eye to toggle between the two options.

    Zoomer

    To zoom in or out of the score, hold Ctrl and scroll the mouse wheel up or down respectively.

    Menus Contextuels

    To bring up a context menu, right click on the timeline. There are three context menus found in these locations: meta labels, instrument labels, and meta rows.

    Menus contextuels des métaétiquettes

    Upon clicking the right mouse button on the meta labels, a context menu appears that displays all possible meta labels as well as two options: "Hide all" and "Show all." Next to each meta label in the menu, there is a check box that shows if the meta label is currently being shown on the timeline. To show or hide one of the meta labels, select the box of the meta label in the context menu. Selecting "Hide all" will hide all meta labels except for the measures meta. Selecting "Show all" will display all meta labels.

    Menus contextuels des métalignes

    Clicking the right mouse button on the meta rows will display the same context menu as the meta labels.

    Menus contextuels des instruments

    Clicking the right mouse button on the instrument labels will display a context menu with the option to "Edit Instruments." Selecting this will bring you to the same dialog as Edit > Instruments... or pressing I for the shortcut.
