我想附加徽标或更改App Designer uifigure
的整个背景。怎么办呢?
答案 0 :(得分:0)
如果您想为整个数字设置纯色背景,则存在a documented way来执行此操作,例如:
% When creating a new uifigure:
fig = uifigure('Color',[R G B])
% if the uifigure already exists:
fig.Color = [R G B];
uipanel
(uipanel(...,'BorderType','none','Title','','BackgroundColor',[R G B])
)。如果您想将图片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:
如果您想将图片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

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
查找所有活动的网页窗口webWindows = matlab.internal.webwindowmanager.instance.findAllWebwindows();
不幸的是我还没找到,哪个窗口属于哪个UIFigure(你可以使用Title或Position来过滤,但是两个相同的UIFigures会导致问题)。
