Class Method Details

↑ .add_context_menu_handler {|menu| ... } ⇒ Integer

The add_context_menu_handler method is used to register a block of code with SketchUp that will be called when a context menu is to be displayed. The context menu handler can then display the context menu with the items that you have added.

Be careful with what you do in a context menu handler. If you perform an operation takes take a long time, such as traversing the model or selection in a large model it will delay the menu.

See the contextmenu.rb script in the Plugins/examples directory for an example.

Examples:

# Right click on anything to see a Hello World item.
UI.add_context_menu_handler do |context_menu|
  context_menu.add_item("Hello World") {
    UI.messagebox("Hello world")
  }
end

Yields:

  • (menu) —

    A block of code that takes a menu as its only as its only argument.

Returns:

  • (Integer) —

    the number of context handlers that are registered

Version:

  • SketchUp 6.0

↑ .beep ⇒ nil

The beep method plays a system beep sound.

The beep method does not accept any arguments nor return any values.

Examples:

UI.beep

Returns:

  • (nil)

Version:

  • SketchUp 6.0

↑ .create_cursor(path, hot_x, hot_y) ⇒ Integer

Note:

Since SketchUp 2016 it is possible to provide vector images for the cursors. SVG format for Windows and PDF format for macOS. This is the recommended format to use since it will scale well with different DPI scaling.

Note:

Because the image is never released, avoid creating new cursors for the same image for any given tool. Cache it and reuse it.

The create_cursor method is used to create a cursor from an image file at the specified location. This must be called from within a custom tool. See the Sketchup::Tool documentation for a complete example.

The size of the cursor images should be 32x32 pixels.

The coordinates for the cursor's hotspot is based from it's top left corner. For example, a value of (hot_x, hot_y) = (5, 10) would identify the hotpoint of the cursor at 6 pixels from the left edge of your cursor image and 11 pixels from the top edge of your cursor image.

Examples:

class ExampleTool
  def initialize
    @cursor_id = nil
    # Load vector cursor format depending on platform.
    ext = Sketchup.platform == :platform_win ? 'svg' : 'pdf'
    cursor_path = File.join(__dir__, "cursor.#{ext}")
    @cursor_id = UI.create_cursor(cursor_path, 4, 6)
  end

  def onSetCursor
    UI.set_cursor(@cursor_id)
  end
end

Parameters:

  • path (String) —

    File path to an image.

  • hot_x (Integer) —

    An x coordinate that is the “hotpoint” for the cursor computed from the left edge of your cursor image.

  • hot_y (Integer) —

    A y coordinate that is the “hotpoint” for the cursor computed from the top edge of the of your cursor image.

Returns:

See Also:

Version:

  • SketchUp 6.0

Known Bugs:

  • On macOS raster cursors are always displayed at 24x24.

  • In SketchUp 2023.1 on Mac provided an incorrect hotspot location. The hotspot was scaled by a factor of 32.0/24.0. If a hotspot position was greater than 24, the cursor would not display.

↑ .get_clipboard_data ⇒ String?

Returns the plain text available on the clipboard, if there is any.

Examples:

text = UI.get_clipboard_data

Returns:

Version:

  • SketchUp 2023.1

↑ .inputbox(prompts, defaults, title) ⇒ Array<String>, false .inputbox(prompts, defaults, list, title) ⇒ Array<String>, false

Creates a dialog box for inputting user information. The dialog box contains input fields with static text prompts, optional default values, optional drop down selections, and optional title.

You can also use this method to display drop down lists of options, by passing an optional param.

Examples:

# With three params, it shows all text boxes:
prompts = ["What is your Name?", "What is your Age?", "Gender"]
defaults = ["Enter name", "", "Male"]
input = UI.inputbox(prompts, defaults, "Tell me about yourself.")

# With four params, it shows a drop down box for prompts that have
# pipe-delimited lists of options. In this case, the Gender prompt
# is a drop down instead of a text box.
prompts = ["What is your Name?", "What is your Age?", "Gender"]
defaults = ["Enter name", "", "Male"]
list = ["", "", "Male|Female"]
input = UI.inputbox(prompts, defaults, list, "Tell me about yourself.")

Overloads:

  • .inputbox(prompts, defaults, title) ⇒ Array<String>, false

    Parameters:

    • prompts (Array<String>) —

      An array of prompt names appearing in the input box adjacent to input fields.

    • defaults (Array<String>) —

      An array of default values for the input fields.

    • title (String) —

      The title for the input box.

  • .inputbox(prompts, defaults, list, title) ⇒ Array<String>, false

    Parameters:

    • prompts (Array<String>) —

      An array of prompt names appearing in the input box adjacent to input fields.

    • defaults (Array<String>) —

      An array of default values for the input fields.

    • list (String, Array<String>) —

      An array containing pipe-separated strings of options.

    • title (String) —

      The title for the input box.

Returns:

  • (Array<String>, false) —

    An array of returned values if the user did not cancel the dialog. If the user canceled the dialog, false is returned. The returned values in the array will be in the same order as the input fields.

Version:

  • SketchUp 6.0

↑ .inspector_names ⇒ Array<String>

The inspector_names method is used to returns the names of all the inspectors. Inspectors are another name for the various floating dialog windows that you can activate from withing SketchUp, such as the Materials window.

Examples:

inspectors = UI.inspector_names

Returns:

  • (Array<String>) —

    an array of strings containing the names of inspectors.

Version:

  • SketchUp 6.0

Known Bugs:

  • Prior to SketchUp 2022.0 “EntityInfo” was not listed.

↑ .menu(menu_name = "Extensions") ⇒ Sketchup::Menu

Note:

The 'Extensions' menu was named 'Plugins' prior to SketchUp 2015. For backward compatibility 'Plugins' still works.

Note:

'Developer' menu was added with SketchUp 2021.1.

The menu method retrieves a SketchUp's menu object with a given name. This is the first step toward adding your own custom items to the bottom of SketchUp's menus.

Valid menu names are: 'File', 'Edit', 'View', 'Camera', 'Draw', 'Tools', 'Window', 'Extensions', 'Help' and 'Developer'.

Examples:

tool_menu = UI.menu("Tools")
tool_menu.add_item("Cheese Tool") {
  UI.messagebox("Cheese activated.")
}

Parameters:

  • menu_name (String) (defaults to: "Extensions") —

    The name of a supported menu.

Returns:

Version:

  • SketchUp 6.0

Known Bugs:

  • In versions prior to SketchUp 2018 this would crash if you passed an empty string.

↑ .messagebox(message, type = MB_OK) ⇒ Integer

Creates a dialog box containing static text with a series of buttons for the user to choose from.

Valid message box types are:

  • MB_OK - Contains an OK button.

  • MB_OKCANCEL - Contains OK and Cancel buttons.

  • MB_ABORTRETRYIGNORE - Contains Abort, Retry, and Ignore buttons.

  • MB_YESNOCANCEL - Contains Yes, No, and Cancel buttons.

  • IDNO

In an MB_MULTILINE message box, the message is displayed as a multi-line message with scrollbars (as needed). MB_MULTILNE also allows a third string argument that will be used as the title for the messagebox.

Examples:

result = UI.messagebox('Do you like cheese?', MB_YESNO)
if result == IDYES
  UI.messagebox('SketchUp likes cheese too!')
end

Parameters:

  • message (String) —

    The message that you want to display.

    The title to apply to the open dialog box.

  • directory (String) —

    The default directory for the open panel.

  • filename (String) —

    The default filename for the open panel. On Windows, you can alternatively pass a wildcard filter using this format: UIname|wildcard||. Additional filter dropdown list items can be added by adding additional pairs of filter name and filter like this: UIname1|wildcard1|UIname2|wildcard2||. Also multiple wildcard filters can be combined into a single line using a semicolon-separated list in the filter field: ui_name|wildcard1;wildcard2||.

Returns:

  • (String) —

    the full path and name of the file selected, or nil if the dialog was canceled.

See Also:

Version:

  • SketchUp 6.0

Known Bugs:

  • Fixed in SketchUp 2014: Wildcards were not working properly from SU7 to SU2013. Wildcard filters did not populate the file type dropdown. The filter string would be shown in the file name field with '*' characters converted to '_' characters. Note, the format of a wildcard filter string has been changed. See the description of the filename parameter below for details.

Parameters:

Returns:

  • (Boolean)

Version:

  • SketchUp 6.0

Known Bugs:

  • Before SketchUp 2019.3 the mac version would URL encode the given URL. This could inadvertently mangle some URLs, if for example if they had URL fragments (# character). The Windows version would not. As of SketchUp 2019.3 both platforms do not perform URL encoding and the API user is expected to provide a valid URL.

↑ .play_sound(filename) ⇒ nil

The play_sound method is used to play a sound file. Valid sound files include .wav and .mp3 files on the Mac and .wav files on the PC.

Examples:

UI.play_sound "Plugins/mediadiscussion.wav"

    an array of strings containing the names of preference pages.

Version:

  • SketchUp 6.0

↑ .refresh_inspectors ⇒ nil

Tells SketchUp to refresh all inspectors such as the Component Browser and the Outliner. This is useful when you need to manually force a refresh after you've made a change to the document via Ruby. Generally, SketchUp will keep these in sync for you, but occasionally it does not, such as when model.start_operation has disabled UI updates.

Examples:

UI.refresh_inspectors

Returns:

  • (nil)

Version:

  • SketchUp 7.0

↑ .refresh_toolbars ⇒ nil

Tells SketchUp to refresh all floating toolbars. This is useful when you need to manually force a refresh after you've made a change to the document via Ruby. Generally, SketchUp will keep these in sync for you, but occasionally it does not, such as when Sketchup::Model#start_operation has disabled UI updates. This only affects macOS, on Windows the toolbars are always refreshing.

Examples:

UI.refresh_toolbars

Returns:

  • (nil)

Version:

  • SketchUp 2018

↑ .savepanel(title, directory, filename) ⇒ String

The savepanel method is used to display the Save dialog box. The path that is returned can then be used inside code to save out a text or image file. See the standard Ruby class File for examples of reading and writing from disk.

Examples:

path_to_save_to = UI.savepanel("Save Image File", "c:\\", "Shapes.jpg")

Parameters:

  • title (String) —

    The title to apply to the save dialog box.

  • directory (String) —

    The default directory for the save panel.

  • filename (String) —

    The default filename for the save panel. On Windows, you can alternatively pass a mask, like “*.txt”, to have all the .txt files display. If you want multiple file types to display, you can supply multiple masks for the filename and separate them with a semicolon, like this: “.txt;.doc”.

Returns:

  • (String) —

    the full path and name of the file selected or nil if the dialog was canceled.

See Also:

Version:

  • SketchUp 6.0

Known Bugs:

  • Fixed in SketchUp 2014: Wildcards were not working properly from SU7 to SU2013. Semicolon-separated lists of wildcards did not populate the file type dropdown. The filter string would be shown in the file name field with '*' characters converted to '_' characters.

  • Fixed in SketchUp 2022.0: if filename begins with a * it crashes on macOS.

↑ .scale_factor ⇒ Float

Note:

SU2017M0 will automatically scale up line width and text size, but will not scale up the points provided to Sketchup::View#draw2d.

Returns the scaling factor SketchUp uses on high DPI monitors. Useful for things like Sketchup::View#draw2d.

Examples:

# Scale a set of points representing 2d screen points to account for high
# DPI monitors.
points2d = [
  Geom::Point3d.new(0, 0, 0),
  Geom::Point3d.new(8, 0, 0),
  Geom::Point3d.new(8, 4, 0),
  Geom::Point3d.new(0, 4, 0)
]
tr = Geom::Transformation.scaling(UI.scale_factor)
points2d.each { |point| point.transform!(tr)

Returns:

  • (Float)

Version:

  • SketchUp 2017

↑ .select_directory(options = {}) ⇒ String, ...

The select_directory method is used to display the OS dialog for selecting one or several directories from the file system.

Examples:

# Default title and folder:
chosen_folder = UI.select_directory

# Custom dialog title:
chosen_folder = UI.select_directory(title: "Select Image Directory")

# Force a start folder:
chosen_folder = UI.select_directory(directory: "C:/images")

# Allow multiple items to the selected:
chosen_folder = UI.select_directory(select_multiple: true)

# Custom dialog title and force a start folder:
chosen_folder = UI.select_directory(
  title: "Select Image Directory",
  directory: "C:/images"
)

Parameters:

  • options (Hash) (defaults to: {}) —

    The dialog can be customized by providing a hash or named arguments of options.

Options Hash (options):

  UI.set_cursor(cursor_id)
end

Parameters:

  • cursor_id (Integer) —

    The id of the cursor you want to display.

Returns:

  • (Boolean)

Version:

  • SketchUp 6.0

↑ .set_toolbar_visible(name, visible) ⇒ Boolean

The set_toolbar_visible method is used to set whether a given toolbar is visible. Note that the toolbars and their names are different on the Mac vs. PC, so be careful and be sure to test when using this method in a cross-platform script.

↑ .start_timer(seconds, repeat = false) {|procedure| ... } ⇒ Integer

The start_timer method is used to start a timer. This is an effective method to create a repeating snippet of code for arbitrary animation.

See this blog post for an detailed example of custom animation using timers: sketchupapi.blogspot.com/2008/10/animate-yo-cheese.html

Note that there is a bug that if you open a modal window in a non-repeating timer the timer will repeat until the window is closed.
