类: Command,HtmlDialog,HtmlDialog,Toolbar,WebDialog

类方法摘要# 崩溃

类方法细节

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

add_context_menu_handler方法是用来向SketchUp注册一个代码块，当需要显示上下文菜单的时候，这个代码块会被调用。然后上下文菜单处理程序可以显示你所添加的项目的上下文菜单。

请注意你在上下文菜单处理程序中的操作。如果你执行一个需要很长时间的操作，比如在一个大的模型中遍历模型或选择，它将延迟菜单。

参见Plugins/examples目录下的contextmenu.rb脚本，以获得一个例子。

例子:

# 在任何东西上点击右键可以看到一个Hello World项目。UI.add_context_menu_handler do |context_menu|
  context_menu.add_item("你好，世界") {
    UI.messagebox("你好，世界")
  }
end

Yields:

  • (menu)—

    一个将菜单作为唯一的参数的代码块。

返回:

  • (Integer)—

    已注册的上下文处理程序的数量

版本：

  • 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

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 Tool class for a complete example.

Since SketchUp 2016 it is possible to provide vector images for the cursors. SVG format for Windows and PDF format for OS X.

Examples:

cursor_id = nil
cursor_path = Sketchup.find_support_file("Pointer.png", "Plugins/")
if cursor_path
  cursor_id = UI.create_cursor(cursor_path, 0, 0)
end

def onSetCursor
  UI.set_cursor(cursor_id)
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. For example, a value of (hot_x, hot_y) = (5,10) would identify the hotpoint of the cursor at 5 pixels from the left edge of your cursor image and 10 pixels from the top edge of your cursor image.

Returns:

  • (Integer)—

    ID associated with the cursor

Version:

  • SketchUp 6.0

↑ .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>

Theinspector_namesmethod 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.

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

Note:

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

Themenumethod 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”.

    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.

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:

  • 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 whenSketchup::Model#start_operationhas 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

Thesavepanelmethod 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: iffilenamebegins 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 toSketchup::View#draw2d.

Returns the scaling factor SketchUp uses on high DPI monitors. Useful for things likeSketchup::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)
