Snap to grid effect with Quartz 2d? iphone dev

由 走远了吗. 提交于 2019-12-06 13:55:38
问题 Still an iphone dev starter but trying. I would like to have the user touch the screen at which point a pin (dot) will be placed on the view. I have accomplished this (yey) but i would like to have snap to grip effect, and can not come up with a solution. This is how i am placing that dot: CGPoint drawPoint = CGPointMake(lastTouch.x - horizontalOffset, lastTouch.y - >verticalOffset); [drawImage drawAtPoint:drawPoint]; //Tell the image to draw itself I have a grid as a background on a

Split screen based on number of items and screen ratio

由 时光毁灭记忆、已成空白 提交于 2019-12-06 13:51:58
问题 I have to split the screen equally (as possible) given a dynamic number of items. So i need to find the number of columns and rows based on the screen size/ratio. Each item size is not important since i will calculate them in % based in the items per col and row. If i have 5 items, then (depending on the screen ratio) i will probably have 3 columns in the 1st row and 2 columns in the 2nd row. That's ok. 回答1: First you have to decide what you mean with "divide the screen equally". It probably

.NET WinForms - Programmatically End Current Edit - DataGridView

由 邮差的信 提交于 2019-12-06 12:42:51
How can you programmatically end the current cell edit without losing the change? I have my DataGridView set to EditOnEnter mode. I tried EndEdit() on the grid but this backs out the current edit. Assuming this is remarkably close to what I've done with the grid and without seeing any code, the only thing I did differently was to follow the call to EndEdit on the DataGridView with a call to EndEdit on the BindingSource. 来源： https://stackoverflow.com/questions/1394364/net-winforms-programmatically-end-current-edit-datagridview

Zurb Foundation 5: Grid Column Stacking

由 家住魔仙堡 提交于 2019-12-06 11:49:08
问题 I'm new to foundation and I only have the basic idea on how to use grids. I have these 3 columns that need to be stacked (see "mobile" image) when viewed on mobile/small screens. It should look something like this when in larger screens: Here's my current code. It's not quite what I wanted, and I'm starting to get confused. <div class="row"> <div class="large-12" style="background-color:#bdc3c7;"> <div class="medium-4 medium-push-8 columns" style="background-color: #1abc9c; border: 1px solid

javafx make a grid of buttons

由 只愿长相守 提交于 2019-12-06 11:46:47
I want to make a grid with a specific amount of buttons. I know how many buttons there are need to be because I get the number of rows and columns. I could do a loop, but I don't know how you can place buttons next to eachother and underneath. Secondly, the buttons need a Text and an Id, text is no problem, but how do you give them an id? And at last, and probably most difficult, it can occur that there are a lot of rows, so that a scrollbar should be available. At the end it should look something like this: @Override public void start(Stage stage) { GridPane grid = new GridPane(); grid

ASP.net Grid paging with merged rows

由 一笑奈何 提交于 2019-12-06 11:27:59
I am currently using GridView to display tabular data. I need to merge cells in the first column that have equal values. At the moment I have code in the PreRender event to set the RowSpan property for me, and it's working fine. The problem is I cannot use paging, since the pages will split in the middle of a section where the first field is equal. I want the record count for paging to count one for each of the merged rows, rather than one for each sub-row. Is this possible with GridView or some other jQuery grid? Instead of handling the merging at the UI level, would it work to prepare the

Create a grid of buttons using a loop in PyQT4

由 风格不统一 提交于 2019-12-06 11:27:42
问题 Is there a way to create a grid of buttons using a loop in PyQT4? So for example, something that has the effect of: for j in range(0, 10): for k in range(0, 10): grid.addbutton(j, k) Thank you. 回答1: Sure there is. QGridLayout might be useful in this case. Here is a minimal example: import sys from PyQt4 import QtGui app = QtGui.QApplication(sys.argv) widget = QtGui.QWidget() layout = QtGui.QGridLayout() buttons = {} for i in range(10): for j in range(10): # keep a reference to the buttons

Magento select field disables row in related products
