write_stringT_write_stringWriteStringWriteStringwrite_string (算子名称)

名称

write_stringT_write_stringWriteStringWriteStringwrite_string — Print text in a window.

参数签名

write_string( : : WindowHandle, String : )

描述

write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string prints StringStringStringStringstringValstring in the output window starting at the current cursor position. The output text has to fit within the right window boundary (the width of the string can be queried by get_string_extentsget_string_extentsGetStringExtentsGetStringExtentsGetStringExtentsget_string_extents).

The font currently assigned to the window will used. The text cursor is positioned at the end of the text.

write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string can output all three types of data used in HALCON . The conversion to a string is guided by the following rules:

strings are not converted.
integer numbers are converted without any spaces before or after the number.
floating numbers are printed (if possible) with a floating point and without an exponent.
the resulting strings are concatenated without spaces.

For buffering of texts see set_systemset_systemSetSystemSetSystemSetSystemset_system with the flag 'flush_graphic'.

注意

If clipping at the window boundary is desired, exceptions can be switched off by set_check(::'~text':)set_check("~text")SetCheck("~text")SetCheck("~text")SetCheck("~text")set_check("~text").

运行信息

多线程类型:可重入(与非独占操作符并行运行)。
多线程作用域:全局(可以从任何线程调用)。
未经并行化处理。

参数表

WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle (input_control) window → (handle)

Window handle.

StringStringStringStringstringValstring (input_control) string(-array) → (string / integer / real)

Tuple of output values (all types).

Default: 'hello' "hello" "hello" "hello" "hello" "hello"

结果

write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string returns 2 ( H_MSG_TRUE) if the window is valid and the output text fits within the current line (see set_checkset_checkSetCheckSetCheckSetCheckset_check). Otherwise an exception is raised.
