问题 I have a list of Vertex objects, each with their own labels and id's. How can I use this list as a model for a wxPython ComboBox such that when a user selects an option, I can immediately retrieve the Vertex id? It appears that ComboBox only accepts strings as a model. I cannot create a dictionary of label to id pairs since there are duplicate labels. I noticed a ComboCtrl class which I can subclass to create a specialized combo box, but I feel like there is a easier solution to this. 回答1:

问题 I stumbled on (in my eyes) a silly problem. However I don't find a solution for this (maybe because of not using the right search keywords, or by making it too difficult when it can be easy..) Scenario: I have a combobox with 500 customers. I have to select a single costumer. In Swing, when the list was down and you started typing, it automatically jumps to the typed letter. E.g.: Items: Adam Dirk Freddy ... Roger Steven Z person When the combobox list is open, I just type 'R' and, in swing,

问题 I've opened up an ExtJs project that I've not had my head in for some time, and this is baffling me. I've an Ext.form.ComboBox that uses a remote JSON store to list users. I use an XTemplate to format the users as listed in the drop down: '<tpl for="."><div class="x-combo-list-item">', '{firstname} {lastname} ({email})', '</div></tpl>' When I expand the drop down, I see my users listed correctly: John Smith (jsmith@company.com) John Ford (jford@company.com) However when I click on a user, the

问题 My goal is to manipulate the text-styles of my application via DependencyProperties. I got a diagram in which the texts are to be manipulated in size, fontfamily, color, etc. So I'd like to use an interface similar to a rich text editor like Word. I'm using this code in my TextStyleVM http://shevaspace.blogspot.com/2006/12/i-have-some-fun-with-formattedtext_14.html So I have a FontFamilyProperty and a Getter and Setter for it: public static DependencyProperty FontFamilyProperty =

问题 In my WPF application, I have a ComboBox that is filled with a static list of ComboBoxItems because its contents will never change. However, because I want to databind the SelectedItem to my underlying ViewModel, I want each ComboBoxItem to also have a separate value that is to be assigned to my ViewModel property. And I'm having a bit of trouble to get this working. My ComboBox declaration looks like: <ComboBox Height="23" HorizontalAlignment="Stretch" Margin="2" Name="comboBox1"

问题 I would like to slide the text (marquee text) of the selected item in a combobox, if it's lenght is bigger than the width of the combobox. It can be either automatical or when the user put the mouse over the combobox. The problem is that i have absolutely no idea on how to do that. It's maybe possible to do that with a render transform (previous definition of a textblock inside it)? or with a storyboard? Here is the xaml that i need to modify <DataGrid.ColumnHeaderStyle> <Style TargetType="{x

问题 I'm using ExtJS 4 and looking for a way I can hide currently selected value from combo's dropdown list? So instead of this ("Alaska" currently selected in combobox): I want the list of values look like this: In my case the combobox is not editable (i.e. you can't input an arbitrary value), I don't think it makes much sense to display the selected value two times: once in the input field and once in the dropdown list. I already see what is selected, I want the dropdown list to only show me

问题 I am using this code to add a value to a combobox different then the one displayed: how to add value to combobox item Lets suppose i have 3 values in my Combobox: item 1 item 2 item 3 If i chose item 2 from the dropdown the code in the link works. But if i TYPE item 2 manually it doesnt work because i think that typing it only sets the combobox1.text value and not the combobox1.selecteditem . I can type a value present in the dropdown, or one not present. If i type one that is present, then
