menubar

问题 this is what I have: this is what I want to get: If there is no pages in navigation stack, then title icon will be in left corner, else there will be back arrow and "Back" text. I didn't find any options to customize it, is it possible at all? 回答1: You can change arrow to hamburger icon if you use your MasterPage within NavigationPage: Detail = new NavigationPage(masterPage); If you want to hide icon - it only applies to Android. It can be solved with custom renderer (http://developer.xamarin

问题 Is it possible to make a window to go over the menu bar, without going in fullscreen? Thanks in Advance! 回答1: Yes, trivially: window.level = NSMainMenuWindowLevel + 1; (Reference: Drawing to the Full Screen, OpenGL Programming Guide for Mac OS X .) sebastianmarkow is correct in that this is terrible behaviour for a normal document window, but there are several window types for which this is normal: cursors, tool tips, and special utilities like Xscope. 回答2: I liked Jens Ayton's answer, but

I do not want a display dialog constantly popping up so I am looking for example,

问题 I have a working application. I added a menuBar() to the main window with some menus. Then, I hid it to free screen space. I wrote the code below so that when user presses ALT key, the menu bar appears if it's hidden, and it hides if it's displayed. void MainWindow::keyPressEvent( QKeyEvent *k ) { if(k->modifiers() & Qt::AltModifier) { menuBar()->setHidden(!menuBar()->isHidden()); if(menuBar()->hasFocus()) { QMessageBox::information(this, "Info", "Focus !"); } } } As you can see, I also added

问题 Vaadin Framework (Vaadin 8) offers a MenuBar widget, as discussed in the manual, and shown in the Sampler. When I switch the manual to "Vaadin 10" mode, I cannot find the MenuBar widget. I know Vaadin 10 (Vaadin Flow) is a major re-write of Vaadin, is the widget changed in name or not yet available? 回答1: Possibly in Vaadin 14 Update: A MenuBar widget is planned for development by Vaadin Ltd, scheduled for Vaadin 14 release.

问题 I've placed at the top of a BorderPane a MenuBar with a "File" Menu and a "Close" MenuItem inside: How can I make it look thinner like the MenuBar s of most of the software I use, similar to the image below? I think it must be simple enough but as a beginner I couldn't really google it. I'm not sure how to name the problem (not many useful results for "javafx menubar height", size, styling, etc.) 回答1: Adding the following selectors to you stylesheet reduces the height of each menu element:

问题 The Problem I am working with a form where the aero glass border is extended from the top around 80 pixels. TMainMenu doesnt support custom positioning out of the box and I only assume it might be possible via owner draw. Drawn on a form in the default position even with double buffered to true the text does not show properly in any version of delphi (07, 09 here tested on 10 XE by friends). What I really want is for the menu to be transparent with black text, and if possible in a lower and

问题 When you create an application with a GUI using Tkinter in Python, the name of your application appears as "Python" in the menu bar on OS X. How can you get it to appear as something else? 回答1: My answer is based on one buried in the middle of some forums. It was a bit difficult to find that solution, but I liked it because it allows you to distribute your application as a single cross platform script. There's no need to run it through py2app or anything similar, which would then leave you

问题 I'd like to make a menubar, which is fixed on the top of the page while scrolling. Something like the top menu in Facebook. Also, I want a div holding the logo float at the left of menubar, and a nav float at the right of the menubar. 回答1: This should get you started <div class="menuBar"> <img class="logo" src="logo.jpg"/> <div class="nav"> <ul> <li>Menu1</li> <li>Menu 2</li> <li>Menu 3</li> </ul> </div> </div> body{ margin-top:50px;} .menuBar{ width:100%; height:50px; display:block; position
