When I set the indentation level to 1 for a QTreeView, the view no longer requests the data for child items of the top level. So I just end up with top level items. The items have children, but no data is requested of the children
When indentation level is set to 0, the child items are requested and I get child items displayed and the top level items have the expanders to hide or show the children.
So what could be the problem with setting the indentation level to 1?
EDIT: The problem was my assumption that an indentation level of 1 represented an indentation of one tree view column. Actually it is the number of pixels to indent. Low indentations cause the text to be displayed over the expansion widget, so it looks like there are no children. I had also assumed the default indentation level was 0, which is why I assumed it worked. The default is 20.

We try to use the treefilter in IcCube to show categories with subcategories. Now we discovered two problems, we don't know, how to fix:
We have 15 categories on level 1, but only the first 11 of them show. There is some space underneath, so it doesn't seem to be cut due to rendering:
We are not able to activate a vertical scrollbar, so when we unfold the tree, there are parts we cannot see anymore. The hotizontal scrollbar is there, but once the tree is too big (image 2) it can't be used anymore as well.
Did we do something wrong and there are options we didn't see, or are our problems due to some bugs in this widget?
Point 1)
Try to increase Max Member Count property on the Query Wizard tab of the widget (this number is for all the members to be managed, not only level 1 items)
Point 2)
Try adding {"cssStyle":"overflow:auto"} in the Content CSS property of the Box tab of the widget.
We have a script that export our Indesign documents to HTML and one of the routine is to export tables. In this script we go throught each Tables->Rows->Cells and evaluate some of the properties (i.e. bottomEdgeStrokeType, topEdgeStrokeType, etc...) and transport them to HTML.
Now yesterday we had problem converting one particular document because some cells were missing the "bottomEdgeStrokeType" property entirely. I've discovered this by outputting the properties of each cells and compare the faulty ones with the others.
This line bellow was trowing the error: "Invalid object for this request.".
var cellType = cell["bottomEdgeStrokeType"];
Now, to fix this I've wrapped this around a try catch block to handle the case when it's not there, but now what is puzzling me is how on earth can Extendscript instantiate an object with missing properties?
Indesign version: CS5.5
A property is not only 'undefined' if it cannot exist at all (such as asking for the parent text frame for a character in overset text), but InDesign's Javascript engine also fails to return a reasonably accurate result for multiple values.
If you ask for "the" point size of a paragraph, where this paragraph contains multiple sizes, poor ID does not consider to return something like CONSTANT.Mixed, or the first value only, or (what I might have preferred) an array of the values; it returns undefined instead.
So how can a single table cell have multiple bottom strokes? If the cell underneath it is split into multiple cells, and one has a "top" stroke but the other has not.
It's difficult to recommend an adequate solution. You could first test if the current cell is "merged" (as far as InDesign's internal table model is concerned) with columnSpan; and if so, iterate over the number of columns spanned and test the next row's cells for their top stroke, which in theory should match the bottom stroke of the cell above. (I find myself wondering if this is always true. ID's table model is ... weird. It's not entirely like a HTML table, despite the functional overlaps.)
If columnSpan is greater than 1 and equal to the number of cells immediately below the current one, you could test if all of their "top" values are the same and if so use that value. (I never tested this so ID's table model may simply fail because a cell is merged, regardless of same-values or not.)
One could attempt to flag this cell's next row to output "top" strokes as well -- but alternating top and bottom strokes may not align nicely in CSS, side to side. Perhaps it's best to translate only the first top stroke value to "the" bottom stroke property for your current cell, and fix up manually where needed (how?) or, a reasonable action, hope that no-one will ever notice it.
I am using a ZedGraphControl in a WindowsForms project in C#. The ZedGraphControl is V5.1.5.
The data in the control is static and I add it all before the form is shown. The X axis of the data consists of numbers indicating seconds offset from the beginning. in other words from 0 to some number of seconds.
I want to initially show the last 5 seconds, but provide a horizontal scrollbar so the user can scroll back and forth. I set the "graphPane.XAxis.Scale.Max = maxX;" where maxX is the largest X value in my data. I set the "graphPane.XAxis.Scale.Min = maxX - 5;".
The data starts off displaying the way I want it, but when the user scrolls the horizontal bar, bizzar behavior occurs.
As you drag the thumb of the scrollbar to the left, the beginning of the data shown in the grid moves to the lower values as expected, and the thumb of the scrollbar moves to the left, but the right edge of the thumb stays at the right of the scrollbar and you cannot move back to the right. It is as if the data to the right of the viewing range gets truncated as you scroll left.
I cannot find any reason for this nor any way to control it. Does anyone have any ideas about this behavior?
Ok, found it myself.
I found a fine article that describes scrolling:
Add a ScrollBar
In it the author specifically says "the scrolling will be wacky because the scrollable range has not been set".
I used the sample "Manually Setting the Scroll Range" and the part that I was missing is setting the zedGraphControl1.ScrollMinX and zedGraphControl1.ScrollMaxX properties. Once I defined these values everything started working as expected. I also found that in my case, the value of zedGraphControl1.IsAutoScrollRange had no effect, but I left it set to false to be consistent with the example. This would probably have an effect if the dataset is dynamic.
I am building an InDesign panel with ExtendScript which finds text and shows it to the user. To do this, I use the showText() method of the Character object. The problem is that sometimes the text I'm looking for doesn't appear because, even though the method does show the right page at the right place, the text has overflown and is not visible.
Is there a way to check if the text is visible or not? Ideally, I would like to be able to fall back on the story editor if the text cannot be seen as-is...
To check the situation for an individual character, see the parentTextFrames property, it returns an array with 0 or 1 frames. In rare cases of insertion points whose left side is in one frame while the right side is in the following, you get two frames.
app.selection[0].characters.item(0).parentTextFrames.length
You can also compare the index of your character against the last index in the last text container of the story, e.g.
app.selection[0].parentStory.textContainers.pop().characters.lastItem().index
Of course you should first see whether there is overflow at all ...
app.selection[0].parentStory.overflows
You may call the baseline property for the text in a try/catch statement. If text is visible, baseline will return a value, otherwise it will raise an error.

I’ve come across a problem with Windows list controls (I am specifically using MFC, but it looks like it applies to all list controls in the Windows common controls library).
In my specific case, I want to create a list control that has two or more columns. The first column (0) is text-only and is used to allow the user to jump to entries by typing the text in that row. Column two (or three, or four, or whatever) has an image (or an image and text; either way).
This much is all well and good and can be done easily without problem, however the final list control then ends up having a space to the left of the text in column 0 (it may be on the right on an RTL system). This spacer appears to be reserved for an image and I cannot figure out a way to prevent it. (Arranging the specific order of the columns did not change anything.)
Looking around, I found some other people complaining of the same thing, specifically this thread which leads to this thread. The proposed solution does not work because as was stated, simply shrinking the width of column zero merely cuts off the text rather than the image spacer (plus, you then have to prevent and/or process any changes to column widths that the user tries to make).
Does anyone have any ideas of how to fix this bug short of writing a list control from scratch or using one of the too-fancy grid controls on CodeProject/CodeGuru/etc.?
Thanks a lot.
Did you try to change the iIndent member of the LVITEM struct? MSDN says this:
iIndent Version 4.70. Number of image widths to indent the item. A
single indentation equals the width of
an item image. Therefore, the value 1
indents the item by the width of one
image, the value 2 indents by two
images, and so on. Note that this
field is supported only for items.
Attempting to set subitem indentation
will cause the calling function to
fail.
Column 0 is special in a ListView. As soon as you assign a small image list to the ListView, the control expects you to show an image in column 0, so it leaves space for it.
Solutions:
make column 0 zero-width, give it the value you want the user to be able to type. Column 1 becomes your "first" text column. Columns 2+ are for your images. You need full row select style for this to work. Yes, you have to prevent the user from resizing column 0. Yes, that is a pain.
make a column that does have an image to be column 0 and use LVM_SETCOLUMNORDERARRAY to rearrange the display order
owner draw the items.
give column 0 an icon (just to cover all bases)
