问题 I want to create a GUI with tkinter in python using grid-Method and grid_columnconfigure/grid_rowconfigure. Unfortunately, this is not working inside a Frame. How can I get this work? from tkinter import * master = Tk() master.state('zoomed') f = Frame(master, width=800, height=400) Label1 = Label(f, text='Label 1') Label2 = Label(f, text='Label 2') f.grid_columnconfigure(0, weight=1) f.grid_columnconfigure(2, weight=1) f.grid_columnconfigure(4, weight=1) Label1.grid(row=0, column=1) Label2

问题 In my scenario, the end user customizes his or her user interface by breaking it into rows and defining the height rule for those rows (fixed, fill space, fit content). I implement this using the WPF Grid. The Grid starts filling the entire screen, and should not get any bigger - the user MUST be able to see the entire Grid at all times (scroll bars WITHIN rows are okay, but not scroll bars for the entire grid). The crux of my problem: When the user creates one or more "auto" sized rows, the

问题 I am building a ListView that needs to have five columns - the first one needs to have text that can be any length and needs to wrap whenever the window size changes (in addition to changing the row height so the wrapped text is visible) and the other four columns are a static width of 45. I've been searching for hours on this and every solution I come across either requires a static width or doesn't work. Solutions tried: Column widths of auto, 1*, 2*, etc. (settings ignored) DockPanel

问题 Here I write some application, which shows my location. In the emulator I get this: But in device I see this: I connect through wifi, hence there's no problem with internet, it should have opened the map. What is the reason? How can I solve this? Thanks. Addition I just regenerated my API key with keytool. Got the same key I had before. Still the same view in the phone. 回答1: Its Google map API key issue you have to re-generate the API key using the keystore which you are using to export your

问题 I am trying to draw a line across two ggplot histograms in a gtable_matrix, so that the mean of the values in the one histogram is overlaid across both plots. However, I cannot get at the device coordinates of the plotting area. In base graphics, I would use grconvertX(), but where can I find the device coordinates of the plotting area of ggplot so I can convert numbers on my 'user' scale (0-10) to device coordinates? In the example below, I have meticulously found the numbers to plug in to

问题 I've got a grid, currently with three columns. The first column contains a WrapPanel. The second column takes up whatever space is left, and the third column is a fixed width. I want the user to be able to re-distribute the space between the first and second column - that is, some form of dragable division between the two columns, that will resize them accordingly. Any pointers would be appreciated. I'm not sure where to start! 回答1: I think you want to look into a GridSplitter: http://msdn

问题 I have a checkbox for each row within a kendo grid. If the user sorts or filters the grid, the checkmarks are cleared from the checkboxes. How can I prevent the checkboxes from unchecking or re-check them after the sort or filter occurs? Please refer to the following js fiddle to observe the behavior during sorting: http://jsfiddle.net/e6shF/33/ Here's the code on the jsfiddle for reference (...needed to ask this question): $('#grid').kendoGrid({ dataSource: { data: [{id:3, test:'row check

问题 In protractor, I want to verify whether added value is displaying in the grid. How do I validate it? The grid looks like this: 回答1: Try it at your end and let me know it works: var a = element(by.xpath("//div[contains(text(), 'test_protractor')]")).getText().then(function(msg){ console.log(msg) expect(msg).toEqual("test_protractor") }) If there are multiple and you want to get only first row then var a = element.all(by.xpath("//div[contains(text(), 'test_protractor')]")).get(1).getText().then

问题 i am working with Ext JS & Rails as backend..i am having myysql database that has parent-child relationship i.e. 1-to-many relationship...I want a "single" JSON store that can be used to load "GRID" data with parent & child records.. Also is there any way to bind both - the form as well as the grid to the same store but having different jsonreaders? i.e. form's datareader would read the string with root: 'customers' and grid will read the string with root :'products' ?
