layout

问题 So I am a computer science student and I've finished my first year. I wanted to create a simple program and I realized that I am so tired of using no layout; this.setLayout(null); It is so tiresome to add bounds to every single component. Well, I have been using JPanel components and GridLayout a lot, which have made my work a bit easier. But I am tired of it. I care very much about the look of the GUI I make and use almost half the time programming to make the GUI look good before I start

问题 I seem to have problems using custom styles for ListView. All online searches (stackOverflow and other sites) pty much say the same: - create an my_style.xml layout file. - use it in the adapter. But for some reason this doesn't seem to be working for me. MainAct.java: arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.list_content, items); XML file: <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id

问题 I'm arranging images in a grid with MigLayout. I could get the width to take the whole space available in the column, but then I want the height to grow accordingly so the proportion of the image still fixed. What is the best approach for this? Could I do that with an expression in the constraint or I have to override the getPreferredSize()? Thanks! 回答1: After a lot of researching, I realize that there is no nice way of doing this with Swing. The problem is not only coming from MigLayout but

问题 I'm trying to achieve with kind of layout inhtml/css/jquery (see attach file) Does anybody have any idea how this can be done ? I tried to put a css shape or svg for the line - which is fine, but how to make the text going this format ? Any highlight would be incredible, From my research I can't find any information like that ! thank you foe your time :) EDIT: what about this format ? 回答1: Here's one possibility in JS. It basically amounts to inserting floated divs of increasing widths, each

问题 unfortunately, the answers to this question that I have found do not work for me. I think I make a mistake somewhere... I want to add content to a QGridLayout: int rows = 2; int columns = 2; for(int i=0; i<rows; ++i){ for(int j=0; j<columns; ++j){ QVBoxLayout *layout = new QVBoxLayout(); QComboBox *c1 = new QComboBox(); QComboBox *c2 = new QComboBox(); layout->addWidget(c1); layout->addWidget(c2); ui->gridLayout->addLayout(layout,i,j); } } I now want to change the content of this QGridLayout.

问题 I am designing a product emulator in WPF. Our company sells a handheld electronic medical device, and we'd like to experiment with user interaction with a "virtual", skinned (sort of) GUI to represent buttons and leds. Is there a way to "force" WPF to display stuff with its real-world dimension on the screen (by getting monitor dpi information, or something like this)? As another example, suppose I can layout a plastic, standard-sized Credit Card using WPF controls (DockPanels, Labels,

问题 I have a ListView with some Labels in it. The labels' width property is bound to the width property of the ListView but they seem to be slightly larger meaning that a horizontal scrollbar is shown on the list view. What I want is to fit the labels in the list view without the scrollbar on the bottom. I have looked at various padding and insets values on both the label and the list view but none I have found are the culprit (most are zero). Here is an example which demonstrates the problem.

问题 I have a function that creates a grid of similar 2D histograms. So that I can select whether to put this new plot on a pre-existing figure, I do the following: def make_hist2d(x, y, current_fig=False, layout=(1,1,1),*args): if current_fig: fig = _plt.gcf() ax = fig.add_subplot(*layout) # layout=(nrows, ncols, nplot) else: fig, ax = _plt.subplots() H, x, y = np.histogram2d(...) # manipulate the histogram, e.g. column normalize. XX, YY = _np.meshgrid(xedges, yedges) Image = ax.pcolormesh(XX, YY

问题 I have been trying many solutions out there for preventing the soft keyboard from pushing my layout when it appears. However, all solutions did not work. Simply, I want everything in my layout (buttons, imageViews, Background, textViews, textEdits) to stay in place when soft keyboard is shown. I do not care about what it will cover. I tried all of the following and all produced the same output and do not work: (did not work) I tried writing android:windowSoftInputMode="adjustNothing" in my

问题 I need change center of some views programmatically. 10 or more. I don't want to adding each bottom constraint as outlet, so could I search them from code like as: for(NSLayoutConstraint *constraint in view.constraints) Which attributes should I check? I need constraint for bottom space of superview. 回答1: Have you heard about IBOutletCollection ? When you link any object from IB to VC code, in popup window you can select IBOutletCollection Option. After link all constraints you want, only
