01. 概述

dev_set_preferences - 在程序中設置HDevelop的preferences。

02. 簽名

dev_set_preferences( : : PreferenceNames, PreferenceValues : )

03. 描述

dev_set_preferences可以在程序中設置HDevelop的特定的preferences 。 此算子支持以下preferences ：

‘graphics_window_context_menu’:

控制右鍵圖形窗口是否打開context menu。 默認情況下，context menu已啟用。 如果鼠標右鍵用于控制圖形窗口中的某種navigation，例如移動或縮放3D對象，則禁用context menu可能是合理的。

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘graphics_window_mouse_wheel’:

控制是否可以使用鼠標滾輪放大圖形窗口的內(nèi)容。 默認情況下，鼠標滾輪已啟用。 如果圖形窗口顯示3D對象objects ，并且如果在3D display 算子的幫助下交互地實現(xiàn)對象的縮放，禁用鼠標滾輪是合理的。

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘graphics_window_tool_tip’:

控制在圖形窗口上按下Ctrl鍵是否在鼠標光標下顯示當前像素位置和灰度值的 tool tip。 默認情況下， tool tip已啟用。 如果程序基于用戶交互（例如，用于操縱3D對象上的視圖）而判斷Ctrl鍵的狀態(tài)，則禁用工具提示可能是合理的。

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘suppress_handled_exceptions_dlg’:

控制是否應該抑制錯誤對話框，該對話框默認是開啟的。在程序運行期間某一程序行發(fā)生錯誤并且由try-catch塊封閉，有此可以由異常處理程序處理，對話框也會默認打開。 該選項永久存儲在HDevelop.ini文件中，也可以通過Preferences dialog / General Options / Experienced Users進行配置。 如果一個沒有被try-catch塊包圍的程序行引發(fā)異常，總則是打開一個錯誤消息對話框。

Possible values: ‘false’, ‘true’.

Default value: ‘false’ (Any changes are persistently saved).

原文描述：

dev_set_preferences allows to set selected preferences of HDevelop within a program. The following preferences are supported:

‘graphics_window_context_menu’:
Controls whether a right click into the graphics window opens a context menu or not. By default the context menu is enabled. Disabling the context menu may be sensible if the right mouse button is used for controlling some kind of navigation in the graphics window, e.g., for moving or zooming 3D objects.

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘graphics_window_mouse_wheel’:
Controls whether a the mouse wheel can be used to zoom the contents of the graphics window or not. By default the mouse wheel is enabled. Disabling the mouse wheel may be sensible if 3D objects are displayed and if the zooming into the objects is realized interactively with the help of 3D display operators.

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘graphics_window_tool_tip’:
Controls whether pressing the Ctrl-key over the graphics window shows a tool tip with the current pixel position and the gray values under the mouse cursor or not. By default the tool tip is enabled. Disabling the tool tip may be sensible if the state of the Ctrl-key shall be evaluated for program based user interactions, e.g., for manipulating the view on 3D objects.

Possible values: ‘false’, ‘true’.

Default value: ‘true’.

‘suppress_handled_exceptions_dlg’:
Controls whether the error dialog should be suppressed that is by default opened for exceptions that are thrown during program execution and that are enclosed by a try-catch block and can therefore be handled by an exception handler. This option is persistently stored into the HDevelop.ini file and can also be configured via the Preferences dialog / General Options / Experienced Users. If an exception is thrown by a program line that is not enclosed by a try-catch block, an error message dialog is always opened.

Possible values: ‘false’, ‘true’.

Default value: ‘false’ (Any changes are persistently saved).
