How can I select multiple rows in UITableView

由 若如初见. 提交于 2019-12-01 10:48:19
I want to display some selected contacts in a list and then I need a feature to select multiple contacts at a time and then on clicking a button it should trigger an email to the selected contacts. For this I am using UITableView to display the contacts but I am not able to find any way to unable the multiple selection for UITableView. On doing some google search I found that UITableView does not support multiple selection. Is there any way to select multiple rows in UITableView or which control should I use for this purpose. Thanks in advance. Gaurav Check the Apple's Sample Code for this

Go to a item in Listview without using smoothScrollToPosition

由 核能气质少年 提交于 2019-12-01 10:32:26
I'd like to go to (display) a specific item in my listview but without scrolling. I don't want any animation but I'd like to be instantaneously transported to the desired item. I'm using a checkable listview : mylistview.setChoiceMode(1) . I understood that mylistview.setSelection(position) is the solution, but when I use it, nothing happens (maybe because it's a checkable listview ?). When I use mylistview.smoothScrollToPosition(position) , it works well but I have obviously this scroll animation which I don't want. What could I do ? Thanks. Try this out: myListView.post(new Runnable() {

Get data from selected row of gtk treeview - gtkmm, c++

由 我怕爱的太早我们不能终老 提交于 2019-12-01 06:56:00
I have a GTK application that has a window with a treeview and a button. When the button is clicked I need to get the data from the first (and only) column of the selected row in the treeview . This is the class for the columns: class ModelColumns: public Gtk::TreeModel::ColumnRecord{ public: ModelColumns(){ add(m_port_name); } Gtk::TreeModelColumn<Glib::ustring> m_port_name; }; This is like in the example here but with only one column: http://www.lugod.org/presentations/gtkmm/treeview.html This is the button click signal handler at the moment: tvPorts is the treeview widget tvPortsList is the

由 我怕爱的太早我们不能终老 提交于 2019-12-01 06:18:13
I'd like to determine if there is an InlineUIContainer (or BlockUIContainer) at the current Caret position in a WPF RichTextBox.

I can do it using the

ExtJS 4 - Grid - Disable rowselection for specific column

由 喜夏-厌秋 提交于 2019-12-01 05:51:54
I have created a grid with extjs 4. The selection.CheckboxModel is implemented to. This means that the row is selected/deselected wherever you click on the particular row. Now i want to disable this selection on the last column since it contains custom buttons. (I don't want to select the row if a button is clicked). Any idea's how to do this? Many thanks in advance! This is actually a tricky little problem, if only because Sencha documentation is lacking. The CheckboxModel does indeed have a beforeselect event inherited from Ext.selection.RowModel . However, there's no easy way to get the
