Is there a method Revit API where I can select elements in order, highlighting the elements selection.
Please note, Selection.PickObjects() does the selection & highlighting but does not save the elements in the order of Selection.
It is exactly as you say. No, the Revit API does not provide a built-in method providing the functionality you require. You can implement it yourself by calling PickObject repeatedly in a loop and collecting the selected elements in your own sorted list.
The easiest way you can fix your problem is by using the following method.
public List<Element> GetElementsBySelection(UIDocument uiDoc)
{
bool flag = true;
List<Element> listElem = new List<Element>();
do
{
try
{
Reference referencia = uiDoc.Selection.PickObject(ObjectType.Element);
Element elem = uiDoc.Document.GetElement(referencia);
listElem.Add(elem);
}
catch (Autodesk.Revit.Exceptions.OperationCanceledException e)
{
flag = false;
}
} while (flag);
return listElem;
}
This method ends when you press the "Esc" key. Other more elegant ways to detect when the key is pressed were discussed in the following forums: Monitoring keyboard and Detect key press.
I hope that it serves as a guide so that you can continue advancing in the development. Best regards.
Thanks to Jeremy Tammik for the general idea to solve the problem.

I have an concept in Jetbrains MPS which I would like to create a custom editor for.
The concept have a number of children.
For each child I would like to display the child's own editor but with a "-" in front of it.
I'm not completely sure I'm trying to solve this in the right way.
But my first attempt is a custom cell looping over the child nodes.
My problem is that I can't figure out how to find the editor cell of the child nodes:
My cell provider:
return new AbstractCellProvider(node) {
#Override
public EditorCell createEditorCell(EditorContext ctx) {
EditorCell_Collection cells = EditorCell_Collection.createVertical(ctx, node);
foreach n in node.elements {
EditorCell_Collection a = EditorCell_Collection.createHorizontal(ctx, node);
EditorCell_Label label = new EditorCell_Constant(ctx, node, "-");
a.addEditorCell(label);
cells.addEditorCell(a);
how to add the child node's editor here?
}
return cells;
}
What are you really trying to achieve? An example might help here...
Without further context (so I may misunderstand your problem), I think you could use an EditorComponent (https://www.jetbrains.com/help/mps/editor.html#editorcomponentsandeditorcomponentcells) for the original editor and then make an editor with a "-" constant followed by the EditorComponent to achieve the desired effect.
I am trying to remove the PreSearch filer and my code is as below. How can I achieve the same?
Xrm.Page.getControl("productid").removePreSearch(function () {
Object
});
Xrm.Page.getControl("productid").addPreSearch(function () {
fetchxml2();
});
function fetchxml2() {
var fetchXml1 = "<filter type='and'>"
fetchXml1 += "<condition attribute='productid' operator='in' >";
for (var i = 0; i < Itemid.length; i++) {
fetchXml1 += "<value>" + Itemid[i] + "</value>";
}
fetchXml1 += "</condition>";
fetchXml1 += "</filter>";
Xrm.Page.getControl("productid").addCustomFilter(fetchXml1);
//Xrm.Page.getControl("productid").removePreSearch(fetchXml1);
};
In order to be able to remove the handler via removePreSearch, avoid using an anonymous function by creating a named function and using that in both addPreSearch and removePreSearch:
function preSearchHandler(){
fetchxml2();
}
Xrm.Page.getControl("productid").removePreSearch(preSearchHandler);
Xrm.Page.getControl("productid").addPreSearch(preSearchHandler);
Just wanted to add this to the discussion:
If you, say, have three different custom filters on a lookup field, the functionality will stack when you apply a new filter.
For example, if you have an option set that calls addPreSearch() on the field, if you select all three different options, you will have all three filters applied to the field simultaneously.
say the option set has three options of [option A, option B, option C],
the corresponding functions are, for simplicity [filterA, filterB, filterC],
on the change event of the option set, for each filter that you apply, simply remove the other two (in this case).
if (optionSet == 810500000) {//option A
Xrm.Page.getControl('lookup').addPreSearch(filterA);
Xrm.Page.getControl('lookup').removePreSearch(filterB);
Xrm.Page.getControl('lookup').removePreSearch(filterC);
}
else if (optionSet == 810500001) {//option B
Xrm.Page.getControl('lookup').addPreSearch(filterB);
Xrm.Page.getControl('lookup').removePreSearch(filterA);
Xrm.Page.getControl('lookup').removePreSearch(filterC);
}//so on and so forth
I hope this helps someone out, I was able to apply custom filters to a lookup based on four distinct selections and remove the "stackable" filters by addition and removal in this manner. It's a little ugly, but, hey, it works. At the end of the day, sometimes the most elegant solution is to just win, win win win win.
If you need more context (fetchXml) and such, I can post that, too...but it doesn't really go along with the point I was trying to make. These filters can be applied simultaneously! That's the main idea I wanted to convey here.
public HtmlComboBox NetworkSelectBox
{
get
{
HtmlComboBox networkSelectBox = new HtmlComboBox(ConfigVMPage);
networkSelectBox.SearchProperties[HtmlComboBox.PropertyNames.Id] = "vnic";
networkSelectBox.SearchProperties[HtmlComboBox.PropertyNames.Name] = "vnic";
networkSelectBox.FilterProperties[HtmlComboBox.PropertyNames.ControlDefinition] = "style=\"WIDTH: auto\" id=vnic name=vnic r";
return networkSelectBox;
}
}
Above is the code I define an UI element and I want to set the property
NetworkSelectBox.SelectedItem = "LabNetworkSwitch";
I've used this way on other elements and all success, but in this one i got the error message
Microsoft.VisualStudio.TestTools.UITest.Extension.ActionNotSupportedOnDisabledControlException: Cannot perform 'SetProperty of SelectedItem with value "LabNetwokrSwitch"' on the disabled or read-only control.
How can I change the control type?
I don't think you want to change the control type. I would suggest trying either waitforready() or find(). What is likely happening is when the control is initially found it is disabled, and find() will sync the actual control with the current networkSelectBox. WaitForReady() is probably the preferable method here though it will implicitly refresh the values of the combo box until it is available for input or the time out has expired.
I doubt you will run into this issue with HtmlComboBoxes but with a couple of WinComboBoxes I have had issues where they could not be set using SelectedItem or SelectedIndex. I ended up doing KeyBoardSendkeys(Combobox,"firstLetterOfItem") until the selected value was correct.
I am using PyQt4 QLineEdit widget to accept password. There is a setMasking property, but not following how to set the masking character.
editor = QLineEdit()
editor.setEchoMode(QLineEdit.Password)
There is no setMasking property for QLineEdit in either PyQt4 or Qt4. Are you talking about setInputMask()? If you are, this does not do what you seem to think it does. It sets the mask against which to validate the input.
To get the control to hide what is typed, use the setEchoMode() method, which will (should) display the standard password hiding character for the platform. From what I can see from the documentation, if you want a custom character to be displayed, you will need to derive a new class. In general however, this is a bad idea, since it goes against what users expect to see.
It's quite easy using Qt: you would need to define a new style and return new character from the styleHint method whenever QStyle::SH_LineEdit_PasswordCharacter constant is queried. Below is an example:
class LineEditStyle : public QProxyStyle
{
public:
LineEditStyle(QStyle *style = 0) : QProxyStyle(style) { }
int styleHint(StyleHint hint, const QStyleOption * option = 0,
const QWidget * widget = 0, QStyleHintReturn * returnData = 0 ) const
{
if (hint==QStyle::SH_LineEdit_PasswordCharacter)
return '%';
return QProxyStyle::styleHint(hint, option, widget, returnData);
}
};
lineEdit->setEchoMode(QLineEdit::Password);
lineEdit->setStyle(new LineEditStyle(ui->lineEdit->style()));
now the problem is that pyqt doesn't seem to know anything about QProxyStyle; it seem to be not wrapped there, so you're stuck, unless you would want to wrap it yourself.
regards
As docs say http://doc-snapshot.qt-project.org/4.8/stylesheet-examples.html#customizing-qlineedit:
The password character of line edits that have QLineEdit::Password echo mode can be set using:
QLineEdit[echoMode="2"] {
lineedit-password-character: 9679;
}
In Qt Designer
Select the line edit, and in the Property Editor window, there will be a property echoMode which you can set to Password.
Using python code
In this case, Anti Earth's answer will work which is:
myLineEdit.setEchoMode(QLineEdit.Password)
I'm writing an event handler to handle the updating of a particular SPItem in a list. The event is asynchronous and I get the SPEvenItemProperties without a problem. What I would like to find out is which of the SPItems columns' actually fired the event. Anyone have any idea how?
Thanks in advance.
Your answer depends a bit on from where and how the SPListItem is retrieved. In a regular list, you do not have access to the previous values of the item. If you turn on versioning, you can get access to the previous versions, depending on permissions, of course.
For a document library you can use the SPItemEventProperties.BeforeProperties to get the previous metadata for a document.
For a document library you can try something like this:
foreach (DictionaryEntry key in properties.BeforeProperties)
{
string beforeKey = (string)key.Key;
string beforeValue = key.Value.ToString();
string afterValue = "";
if (properties.AfterProperties[beforeKey] != null)
{
afterValue = properties.AfterProperties[beforeKey].ToString();
if (afterValue != beforeValue)
{
// Changed...
}
}
}
.b
I think the best way to do this would be to look through the BeforeProperties and AfterProperties of the SPItemEventProperties and check which fields have different values.
These contain the values of all fields of the item before and after the event occurred.
