[英]How to customize the background of an App Designer figure?
我想附上一个徽标或更改App Designer uifigure
的整个背景。 如何才能做到这一点?
如果要为整个图形设置纯色背景颜色 ,则存在记录的方法 ,例如:
% When creating a new uifigure: fig = uifigure('Color',[RGB]) % if the uifigure already exists: fig.Color = [RGB];
uipanel
没有标题或边框( uipanel(...,'BorderType','none','Title','','BackgroundColor',[RGB])
)。 如果要将图像设置为整个图形的背景 :
function q41602238a %% Turn off some warnings: warning off Matlab:structOnObject warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame %% 0. Create a uifigure: app = uifigure(); %% 1. Get a handle to the webwindow: while true try win = struct(struct(app).Controller).Container.CEF; break catch pause(0.1); % Give the figure (webpage) some more time to load end end %% 2. Find the data_tag of the DOM element we want to edit: data_tag = char(struct(app).Controller.ProxyView.PeerNode.getId); %% 3. Manipulate the DOM via a JS command while true try win.executeJS(['dojo.style(dojo.query("[data-tag^=''' data_tag ''']")[0],"background-image","url(https://upload.wikimedia.org/wikipedia/commons/8/80/Wikipedia-logo-v2.svg")']); break catch pause(0.1); % Maybe JS is still not ready. end end
结果:
如果要将图像设置为某个区域的背景 :
function q41602238b %% Turn off some warnings: warning off Matlab:structOnObject warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame %% 0. Create a some element: app = uifigure(); pnl = uipanel(app); %% 1. Get a handle to the webwindow: while true try win = struct(struct(app).Controller).Container.CEF; % disp(win.URL); break catch pause(0.1); % Give the figure (webpage) some more time to load end end %% 2. Find the id of the DOM element we want to edit: data_tag = char(struct(pnl).Controller.ProxyView.PeerNode.getId); widgetId = win.executeJS(['dojo.getAttr(dojo.query("[data-tag^=''' data_tag ''']")[0],"widgetid")']); %% 3. Manipulate the DOM via a JS command dojo_style_prefix = ['dojo.style(dojo.query("#' widgetId(2:end-1) '")[0],']; while true try win.executeJS([dojo_style_prefix '"background-image","url(https://upload.wikimedia.org/wikipedia/commons/8/80/Wikipedia-logo-v2.svg")']); break catch pause(0.1); % Maybe JS is still not ready. end end
结果:
不幸的是我还没有评论,所以这是另一个答案。
从Matlab 2017a开始,Controller不再具有Container属性。 这有效:
warning off Matlab:structOnObject
warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame
win = struct(struct(struct(app).Controller).PlatformHost).CEF;
data_tag = char(struct(app).Controller.ProxyView.PeerNode.getId);
win.executeJS(['dojo.style(dojo.query("[data-tag^=''' data_tag ''']")[0],"background-image","url(https://upload.wikimedia.org/wikipedia/commons/8/80/Wikipedia-logo-v2.svg")']);
还可以使用找到所有活动的webwindows
webWindows = matlab.internal.webwindowmanager.instance.findAllWebwindows();
不幸的是我还没有找到,哪个窗口属于哪个UIFigure(你可以使用Title或Position来过滤,但两个相同的UIFigures会导致问题)。
