两盒软妹~` 提交于 2019-12-01 11:54:12
问题 I do not understand why this does not seem to expand the top-level root items in a QTreeView: # clear existing treeview data model = self.treeview.model().sourceModel() model.clear() # add treeview items here # expand root level items root = model.invisibleRootItem() index = root.index() for i in range(root.rowCount()): item = model.indexFromItem(model.item(i,0)) self.treeview.expand(item) self.treeview.setExpanded(item, True) print 'expanded' 回答1: If you're using a proxy model, you must use

WPF GridViewColumn Width=“auto” only works for items in the current scroll scope

南笙酒味 提交于 2019-12-01 05:49:47
I have a ListView that contains many items and am trying to set the column widths to auto so that they auto-expand to the width of the longest string in the column. At first, it appeared to work, but as I scrolled down the list, I noticed that some of the longer strings were cut short because the column didn't auto-expand enough. Then it occurred to me that setting the width to auto seems to calculate the width based on the column values visible on the grid at the time. So, when I scroll down to rows containing longer strings for a particular column, I can double-click the column divider to

How to create expandable panels using swing?

I would like to create a list of expandand/collapse panels, like on this image: I haven't found any swing component for this, so I began to create something like this. I tried to put buttons one under the other, which fill the available width, but doesn't really works. I can only see the last added one. JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); panel.add(new JButton("Delphi Projects"), BorderLayout.NORTH); panel.add(new JPanel(), BorderLayout.NORTH); // hidden panel panel.add(new JButton("Delphi Projects | Delphi Files"), BorderLayout.NORTH); panel.add(new JPanel(),

Please note the vertical scrollbars shoud show up when needed left columns fits to width right column takes the rest of the space Thanks! Here is one approach that uses CSS only. The HTML looks like: <div id="pageWrapper"> <header>Header</header> <div id="contentWrapper"> <div class="table-wrap"> <div class="cell col1"> <div class="content">Column 1: Shrink-to-Fit Width</div> </div> <div class="cell col2"> <div class="content">Column 2: Variable Width</div> </div> </div> </div> <div id="footerWrapper">Footer</div> </div> and the CSS: html, body { height: 100%; margin: 0; } body { background

WPF TreeView databinding to hide/show expand/collapse icon

ε祈祈猫儿з 提交于 2019-11-30 17:25:28
问题 I implemented a WPF load-on-demand treeview like described in this (very good) article. In the mentioned solution a dummy element is used to preserve the expand + icon / treeview item behavior. The dummy item is replaced with real data, when the user clicks on the expander. I want to refine the model by adding a property public bool HasChildren { get { ... } } to my backing TreeNodeViewModel . Question: How can I bind this property to hide/show the expand icon (in XAML)? I am not able to find

Bootstrap collapse within table/between table rows not working

拥有回忆 提交于 2019-11-30 16:14:08
I have a question regarding the Bootstrap collapse feature. I'm pretty sure that I'm overlooking something quite obvious or easy to fix, but I googled it alot and played with the code, but without success. I have a "account settings" page, where all account information of a user is shown in a table-like format, with the table cells of the last table column always containing an "edit"-button to edit that information. When people click "edit", an edit form shall expand just beneath that table row. I followed the scheme at http://twitter.github.com/bootstrap/javascript.html#collapse , the

bash expand cd with shortcuts like zsh

Is it possible in bash to expand something like cd /u/lo/b <hit tab> to cd /usr/local/bin ? Aserre Sorry I couldn't post earlier, I was held at work, and the bind function was more issue-prone than I first thought. Here is what I came up with : Bind the following script : #!/bin/bash #$HOME/.bashrc.d/autocomplete.sh autocomplete_wrapper() { BASE="${READLINE_LINE% *} " #we save the line except for the last argument [[ "$BASE" == "$READLINE_LINE " ]] && BASE=""; #if the line has only 1 argument, we set the BASE to blank EXPANSION=($(autocomplete "${READLINE_LINE##* }")) [[ ${#EXPANSION[@]} -gt 1

Expand Collapse Expand Issue with JTree Lazy loading

房东的猫 提交于 2019-11-30 14:22:22
问题 I have implemented a tree using Lazy Loading. The 1st level nodes are created at the time of tree creation, where as the child nodes are created only when a user expands any particular node. The data is coming from DB, and we fire a query to the database so as to populate the child nodes. Implemented TreeExpansionListener and using overridden implementation of treeExpanded method. On expansion, I remove all child nodes for the selected node, make a DB query and add the records as child to the
