◆ ShowModeless()

Example of usage:

function plugindef()
    finaleplugin.HandlesUndo = true -- suppresses automatic saving of Undo block
end
 
-- scratch FCString
local str = finale.FCString()
-- create a new dialog
-- it must be a global variable,
-- or else Lua garbage collection may destroy it out from under you
global_dialog = finale.FCCustomLuaWindow()
-- add a button to say "Hello World"
local hello_world_button = global_dialog:CreateButton(0, 0)
str.LuaString = "Hello World"
hello_world_button:SetWidth(100)
hello_world_button:SetText(str)
global_dialog:RegisterHandleControlEvent (
    hello_world_button,
    function(control)
        -- if this modifies the Finale document, first call finenv.StartNewUndoBlock("My Undo Text", false)
        finenv.UI():AlertInfo("Hello World", "") -- replace this with something productive
        -- if updates were successful, call finenv.EndUndoBlock(true)
        -- if updates were not successful, call finenv.EndUndoBlock(false)
    end
)
global_dialog:CreateOkButton()
 
finenv.RegisterModelessDialog(global_dialog) -- must register, or ShowModeless does nothing
global_dialog:ShowModeless()

A fully functioning sample script may be found here.

◆ ShowModelessWithGrabbyFocus()

bool FCCustomLuaWindow::ShowModelessWithGrabbyFocus ( )

inline

Displays the macOS version of the dialog box as a modeless window with grabby focus behavior.

The default focus behavior for modeless plugin dialogs in macOS Finale is that they grab focus whenever possible. This can cause difficulties for users who leave them open while doing other Finale tasks. To mitigate this, the typical behavior for FCCustomLuaWindow modeless macOS windows is to override Finale's grabby focus behavior and instead open a type of window that never grabs focus. (These are similar to the window types of built-in modeless windows like palettes or the Playback Controls.) In very rare circumstances, this can present problems.

Warning: Do not use this function unless there is a specific issue you have to address. The issue is likely to be the need to workaround an annoying Finale behavior. If that behavior is subsequently modified, you could implement a version check to decide which ShowModeless function to use. See the comments at FCMusicRegion::Playback for an example of when you might choose to use ShowModelessWithGrabbyFocus.

The details of how to use ShowModelessWithGrabbyFocus are the same as those for ShowModeless. On Windows there is no difference between them.

Lua-supported (0.68)

◆ TextSelectionChanged()

void FCCustomLuaWindow::TextSelectionChanged ( FCControl * pControl )

inlineoverridevirtual

Virtual handler method for detecing when the text selection changes on edit text controls.

Lua-supported through a callback function.

Parameters

pControl Pointer to the edit text control.

Reimplemented from __FCUserWindow.
