Question

我创建了一个GUI，其中有一个弹出菜单，其中有几个选项（鼠标1 - 鼠标10）可供选择，并且旁边还创建了一个可用的选项。弹出菜单有几个选项可供选择。

我想在弹出菜单和uitable之间进行链接，以便用户选择的每个鼠标 - 一个新的uitable将替换之前的鼠标。

我该怎么做？

这是相关的代码，实际上没什么：

function mouse_number_Callback(hObject, eventdata, handles)


function uitable1_CellEditCallback(hObject, eventdata, handles)

谢谢！

Answer 1

我不确定我是否正确理解了你用什么来解释

用户选择的每只鼠标 - 一个新的uitable将替换之前的鼠标

，反过来，GUI的预期行为。

我已经设置了一个包含table（tag: uitable1）和popupmenu（tag: popupmenu1）的简单GUI。

当用户选择popupmenu中的项目时，table字符串 Selected

的相应行

在uitable1_CreateFcn中，table的内容设置为空字符串
在popupmenu1_Callback中识别出popoumenu中所选项目的索引，并在表格的相应行中打印字符串 Selected 一个被删除。

这是GUI的代码

function varargout = table_gui(varargin)
% TABLE_GUI MATLAB code for table_gui.fig
%      TABLE_GUI, by itself, creates a new TABLE_GUI or raises the existing
%      singleton*.
%
%      H = TABLE_GUI returns the handle to a new TABLE_GUI or the handle to
%      the existing singleton*.
%
%      TABLE_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TABLE_GUI.M with the given input arguments.
%
%      TABLE_GUI('Property','Value',...) creates a new TABLE_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before table_gui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to table_gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% --- Executes just before table_gui is made visible.

希望这有帮助。

一个链接到uitable的弹出菜单，该菜单随弹出菜单上的每个选项而变化（Matlab）
