是否有现成的进度条uicontrol可以添加到Matlab gui, uicontrol或ActiveX组件?

[edit]我知道waitbar函数,我的意思是一个可以在设计的GUI中实现的组件,而不仅仅是弹出窗口。状态栏中的电池状态。

Waitbar及其变体显示一个带状态栏的弹出窗口。在大多数应用程序中,这很好并且使用起来非常简单。

如果要在现有GUI窗口中集成进度条,您有以下几种选择:

  1. 实现内部waitbar代码 - 这实际上只是一个呈现彩色补丁的轴,其宽度取决于进度值。
  2. 使用标准java.swing.JProgressBar,可以通过内置javacomponent function
  3. 添加到您的Matlab GUI
  4. 使用StatusBar utility或解释here向GUI窗口的状态栏添加进度条
  5. 所有这些选择都适用于所有Matlab平台。

是的,有。 waitbar功能是您所需要的。这些示例很容易理解,您可以立即开始使用。它应该适用于所有3个平台(Windows / OS X / Linux)。

根据此MatLab Newgroup评论调整我的代码,我能够整理以下内容:

function h = uiProgressBar(varargin)
%uiProgressBar: A waitbar that can be embedded in a GUI figure.

    if ishandle(varargin{1}) && size(varargin, 2) > 1
        ax = varargin{1};
        value = varargin{2};
        p = get(ax,'Child');
        x = get(p,'XData');
        x(3:4) = value;
        set(p,'XData',x)
        return
    end

    bg_color = 'w';
    fg_color = 'r';
    h = axes('Units','pixels',...
        'XLim',[0 1],'YLim',[0 1],...
        'XTick',[],'YTick',[],...
        'Color',bg_color,...
        'XColor',bg_color,'YColor',bg_color, ...
        'Parent', varargin{1});
    patch([0 0 0 0],[0 1 1 0],fg_color,...
        'Parent',h,...
        'EdgeColor','none',...
        'EraseMode','none');
end

创建如下,其中parent是您要将其添加到的父面板:

myProgressBar = uiProgressBar(parent);

并更新进度条就像这样简单:

uiProgressBar(myProgressBar, .2);

以下是使用figure

的完整工作示例
f = figure('Name', 'Progress Bar Example', 'Position', [100 100 800 600]);

progressBar = uiProgressBar(f);

for i = 1:10:100
    uiProgressBar(progressBar, i/100);
    pause(.5);
end

另一个简单的解决方案是使用两个嵌套的uipanel:

function MyProgressBar(handle, progress)
   % progress = 0.00001 .... 1

   % 1st panel
   p = uipanel(handle);

   % 2n panel as bar
   bar = uipanel(p);
    set(bar, 'BackgroundColor', 'red');
    x = get(bar, 'Position');
    x(3) = progress;       % Corresponds to % progress if unit = normalized
    set(bar, 'Position',x);
end

用法:

 f = figure();
 set(f,'Position',[100,100,400,40]);
 MyProgressBar(f, 0.5); % corresponds to 50% progress

对于任何仍然感兴趣的人,这是我使用课程的解决方案:

classdef progressbar < handle
    properties(Access = protected)
        h_panel         % Panel on which everything sits
        h_ax            % The progress range axes
        h_pbar          % The bar representing progress (patch)
        h_ptext         % Percentage label
    end
    properties(Access = public, Dependent = true)
        range           % Progress range
        pvalue          % Current value
        percent         % Percentage complete (relative within range)
        position        % Position of the object (panel)
        ax_tag          % Tag of the axes
        visible         % Is the object (panel) visible?
    end
    properties(Constant = true)
        default_color = [.75 .75 .9];
    end
    methods
        % Initializer
        function obj = progressbar(fig, pos, range)
            if nargin < 3
                range = [0 1];
            end
            obj.h_panel = uipanel('Parent', fig, 'Units', 'Inches', ...
                'Position', pos, 'Tag', 'progbar_panel');
            obj.h_ax = axes('Parent', obj.h_panel, ...
                'Units', 'Inches', 'Position', [0 0 obj.position(3) obj.position(4)], ...
                'XTickLabel', '', 'XTick', [], 'YTickLabel', '', 'YTick', []);
            obj.h_pbar = patch([range(1) range(1) range(1) range(1)], [0 0 2 2], ...
                obj.default_color, 'Parent', obj.h_ax, 'Tag', 'progbar_patch');
            obj.h_ptext = text(obj.position(3)/2, obj.position(4)/2, '0%', ...
                'Parent', obj.h_ax, 'FontWeight', 'bold', 'Units', 'Inches', ...
                'HorizontalAlignment', 'center', 'Tag', 'progbar_text');
            obj.range = range;
            obj.ax_tag = 'progbar_ax';
        end

        % Property Access Methods
        function set.range(obj, value)
            % Instead of replotting, just reset the XLim to the
            % extremities of the input range. If the values are not
            % increasing, just default to [0 1].
            if value(end) > value(1)
                set(obj.h_ax, 'XLim', value([1,end]), 'YLim', [0 2]);
            else
                set(obj.h_ax, 'XLim', [0 1], 'YLim', [0 2]);
            end
            % Reset progress.
            obj.pvalue = value(1);
        end
        function value = get.range(obj)
            value = get(obj.h_ax, 'XLim');
        end
        function set.pvalue(obj, value)
            % Expects a single value to represent progress value and
            % constructs the selection rectangle from that. If multiple
            % values are passed in, all are ignored but the last, since the
            % left edge of the bar is always the first element of the
            % range.
            set(obj.h_pbar, 'XData', [obj.range(1) value(end) value(end) obj.range(1)], ...
                'FaceColor', obj.default_color);
            set(obj.h_ptext, 'String', sprintf('%3.0f%%', obj.percent * 100));
        end
        function value = get.pvalue(obj)
            % The progress bar is actually 2D, but we treat as if it is 1D.
            % Hence the XData is actually an array of four values but we
            % only consider the second (progress maximum).
            limits = get(obj.h_pbar, 'XData');
            value = limits(2);
        end
        function set.percent(obj, value)
            % Expects a single value between 0 and 1.
            limits = obj.range;
            obj.pvalue = value * (limits(2) - limits(1)) + limits(1);
        end
        function value = get.percent(obj)
            limits = obj.range;
            value = (obj.pvalue - limits(1)) / (limits(2) - limits(1));
        end
        function set.position(obj, value)
            set(obj.h_panel, 'Position', value);
        end
        function value = get.position(obj)
            value = get(obj.h_panel, 'Position');
        end
        function set.ax_tag(obj, value)
            set(obj.h_ax, 'Tag', value);
        end
        function value = get.ax_tag(obj)
            value = get(obj.h_ax, 'Tag');
        end
        function set.visible(obj, value)
            if (isnumeric(value) && value >= 1) || strcmp(value, 'on') == 1 || strcmp(value, 'On') == 1
                set(obj.h_panel, 'Visible', 'on');
            else
                set(obj.h_panel, 'Visible', 'off');
            end
        end
        function value = get.visible(obj)
            vis = get(obj.h_panel, 'Visible');
            value = strcmp(vis, 'on');
        end

        % Public member functions
        function increment(obj)
            % Don't use this if the range is less than 1.
            obj.pvalue = obj.pvalue + 1;
        end
        function display_text(obj, text, color)
            if nargin == 3 && ~isempty(color)
                set(obj.h_pbar, 'FaceColor', color);
            end
            set(obj.h_ptext, 'String', text);
        end
    end
end

声明一个像这样的实例:pb = progressbar(gcf, [1 1], [0 20]);

它可以与相对或实际数字一起使用,即pb.pvalue = 10;pb.percent = .5;在我的示例中执行相同的操作。

我的版本在进度条中间有一个显示当前百分比的文本对象。

还有另外一种方法......对不起,如果它被提及我错过了它。您可以构建一个动态添加条形轴的图形。它非常好用,并且很容易适应自定义应用程序。弹出窗口总是迷路或挡路。
