问题 At the moment I'm currently re-writing a text-based program to have a GUI. One of the problems I am experiencing is that I want the program to wait until a certain condition is met. This condition can be met through the user clicking the "Walk" button until the player.walked attribute = 5. When using a text-based interface this is quite simple, use a while loop and inside have an input function. while (player.getWalked() < 5) { //wait for user input via terminal through the scanner. } However

问题 I'm currently selecting multiple rows in a model tree with the code below. But it can be really slow in big sessions with loads of nodes. I suspect this is not very efficient as it's probably selecting the rows one by one. Is there anything that could speed things up - for example don't refresh while selecting until the last one or select all in one call? selectionModel = self.tree.selectionModel() selectionModel.clear() for node, i in self.tree.model().iterNodeAndIndexs(): if nodeCondition:

问题 I have an existing ComposePopupView() modelview which contains observable this.attachments = ko.observableArray([]); and a method below ComposePopupView.prototype.addDropboxAttachment = function (oDropboxFile) { var oAttachment = null, iAttachmentSizeLimit = Utils.pInt(Settings.settingsGet('AttachmentLimit')), mSize = oDropboxFile['bytes'] ; oAttachment = new ComposeAttachmentModel( oDropboxFile['link'], oDropboxFile['name'], mSize ); oAttachment.fromMessage = false; oAttachment.cancel = this

问题 Please, what do you suggest is the best (in terms of architectural quality) approach to the following scenario: ModelViewA (parent) - requires collection from ModelViewB to display data - access collection multiple times even when the collection remains unchanged ModelViewB (child) - holds collection of items. The collection conceptually belongs to ModelViewB and is primarily modified within this (model)view. However, ModelViewA can also modify the collection The current approach I take is

问题 I'm using QTableView with a subclass of QAbstractTableModel as its model. By implementing data() and headerdata() in the subclassed model, it is feasible to control many properties of the table like data, header values, font, and so on. In my case, I want the model to set the width of each table column. How can this be done? 回答1: There are two ways: In your model's data method you can return the role SizeHintRole. A better way would be to subclass QItemDelegate and override the method. See

问题 I have worked with MVC on the back-end (Rails), and am currently working with MVC(MV*) on the front-end (Angular). I have seen Angular as considered an MV* pattern, but why is it considered that exactly? Using Angular, I understand the separation of concerns, with Views (templates), Controllers, and use Services to serve up data. In this case, the model (data store) via ng-model makes sense for front-end temporary storage, but the actual persistence (when a POST or PUT is made to an API)

问题 I am trying to design a multiview application to use Qt's model/view framework so that I can move lots of complex logic out of my QGraphicsItem classes. As shown in the figure below, the application consists of two (or more) views each containing of an identical series of red vertical guide lines A1 , B1 , C1 ... at the same horizontal positions along each view. I'd like to ensure that when the user drags a guide line one view, say from a point A1 to A_1' as shown in the figure above, all
