Storyboard supports a number of standard actions which are built-in to the
framework. These actions are all prefixed with gra. and can be
incorporated into your application design without any plugin dependency.
Cause a screen transition to occur by replacing the current screen with the new one.
The action arguments are:
The name of the screen to transition to.
Causes a screen transition to occur by fading the old screen into the new one.
The action arguments are:
The name of the screen to transition to.
Defines how the alpha value will change over the transition:
| linear |
| easein |
| easeout |
| easeinout |
| bounce |
The frames per second to use for the transition
The duration of the transition in milliseconds
Release a held screen. If a screen was damaged during the period of time that the screen was being held, then a redraw action will be triggered.
Send an event to the application's input event queue. This action
is equivalent to injecting an event via Storyboard IO or using the Lua
gre.send_event() API
The action arguments are:
The name of the event to send
Change or create a variable value in the data manager.
The action arguments are key/value pairs such that the key is the fully qualified model path for the variable and the value is the new value to assign to that variable. For more information on creating the model paths, see the Data Variables section of this document.
Set the focus to a specific control.
The action arguments are:
The focus index to set the focus to.
The name of a control to set the focus to.
Only one of either the index or the control need to be provided for this action. If both arguments are set, then the index value will be used.
In order for this action to complete successfully, the control sepecified must be set as focusable. For more information about making controls focusable and the focus operation in Storyboard, refer to the Focus section in the Execution Pipeline part of this document.
Move the current focus to the next focusable control.
The action arguments are:
The minimum focus index to move to or -1 to have no minimum value
The maximum focus index to move to or -1 to have no maximum value
In order for this action to complete successfully, there must be a control whose focus index lies between the min and max values. For more information about making controls focusable and the focus operation in Storyboard, refer to the Focus section in the Execution Pipeline part of this document.
Move the current focus to the previous focusable control.
The action arguments are:
The minimum focus index to move to or -1 to have no minimum value
The maximum focus index to move to or -1 to have no maximum value
In order for this action to complete successfully, there must be a control whose focus index lies between the min and max values. For more information about making controls focusable and the focus operation in Storyboard, refer to the Focus section in the Execution Pipeline part of this document.
Move the current focus to the next control in a direction.
The action arguments are:
The minimum focus index to move to or -1 to have no minimum value
The maximum focus index to move to or -1 to have no maximum value
The direction to search for the next focusable control
| up |
| down |
| left |
| right |
In order for this action to complete successfully, there must be a control whose focus index lies between the min and max values. For more information about making controls focusable and the focus operation in Storyboard, refer to the Focus section in the Execution Pipeline part of this document.
Scroll the content of one or more tables.
The action arguments are:
The name of the table control to scroll. May be a comma separated list if multiple tables are specified.
The absolute 1 based row to start the scroll from. The default, 0, indicates that scrolling should start from the current row
The absolute 1 based column to start the scroll from. The default, 0, indicates that scrolling should start from the current column
The number of rows to move. A positive value moves the table down a negative value moves the table up
The number of columns to move. A positive value moves the table right a negative value moves the table left
The frames per second rate at which to scroll the table.
The duration in milliseconds to run the scroll over.
Set the number of rows and columns for a table. This action does not resize the control, simply the number of cells contained within the virtual table.
The action arguments are:
The name of the table control to resize.
The number of rows for the table. Specifying 0 will leave the current number of rows unchanged.
The number of columns for the table. Specifying 0 will leave the current number of columns unchanged.
When the table is resized, a gre.table.resize event will be
emitted.
Navigates the cells of a table, sets the active cell which in turn generates the cell focus events. If the new active cell is not visible the table will be scrolled in order to show this cell.
The action arguments are:
The name of the table control to scroll. May be a comma separated list if multiple tables are specified.
The frames per second rate at which to scroll the table, 0 performs an immediate scroll.
The duration in milliseconds to run the scroll over, 0 scrolls it immediately.
The type of navigation to perform
Sets the active row and column to what is specified in the row/col parameters. The option only ensures that the cell is visible and does not guarantee the cell will be at the top of the visible list.
Move to the next cell, scroll by column then by row
Move to the previous cell, scroll by column then by row
Move to the cell above the current one
Move to the cell below the current one
Move to the cell to the left of the current one
Move to the cell to the right of the current one
Move to the first cell in the table at row,column 1,1
Move to the last cell in the table
The row to navigate to. This is only used if
direction is assigned set
The column to navigate to. This is only used if
direction is assigned set
Use the GRE logging mechanism to output a message.
The action argument is the string message that should be output.
Move a control forward or back in the control z-order heiarchy within its
layer. If the direction is backward or forward
then the control moves in that direction one level. If the direction is
toback or tofront then the control moves
relative to the reference control
The action arguments are:
The name of the control whose z-order is to be changed.
The name of a reference control. Used only when direction is
tofront or toback.
The z-order direction to move the control.
Move in front of reference control, if no reference control is specified then move to front of all other controls on the control's layer
Move in back of reference control, if no reference control then move to back of all other controls
Move one control forward towards the top of the z-order
Move one control backward towards the back of the z-order
Remove a resource which is managed by the resource manager.
The action arguments are:
The pool name containing the resource to dump
The name of the resource to dump
The currently defined resource pools are image containing all
of the images and font containing all of the fonts associated
with the Storybard application.
