问题 I am trying to wrap a DLL, using its header file, through SWIG. I got a syntax error while processing my interface .i file using SWIG. After tracking down what was the offending line (line number of the printed by SWIG error message did not match the true offending line), I found that the minimum non-processable SWIG interface file is: /* example.i */ %module example %{ extern __declspec(dllimport) INT __cdecl function(int argument); %} extern __declspec(dllimport) INT __cdecl function(int

问题 I have an unmanaged dll which contains a class with pure virtual methods only (kind of callbacks): class PAClient { public: __declspec(dllexport) virtual void SetCalculationStarted() = 0; __declspec(dllexport) virtual void SetCalculationStopped() = 0; } Now I have to send these function calls to the managed C# code and decided to use interface for that. This is what I've done: public interface class IPAClientWrapper { void SetCalculationStarted(); void SetCalculationStopped(); }; private

问题 I'm saving an array into a model, when saving the data is not wrapped with Optional (...) however when the data is being read I get the Optional(...) wrapping around it.

This is the reduced

Hiding grid columns change height of rows

阅读更多关于 Hiding grid columns change height of rows

问题 I have quite annoying problem with hiding grid columns dynamically. After I hide columns (with long text in cells), the height of grid rows dramatically increases. Before hide and after hide operation As You can see first row is definitely too high. Probably the reason of that behavior is the fact, that I use text wrap in grid cells. .x-grid-cell-inner { white-space: normal; } Is there any efficient way to make grid rows, not to change their height after hiding columns (and using textwrap ) ?

阅读更多关于 How to find whether text in a text area is wrapped to multiple lines?

问题 How can I find whether a long text in a textarea is wrapped into two or more lines? I'm not talking about the new line chars as discussed here. I'm aware of the plugin Textarea Line Count Any simpler method? 回答1: I experimented on this and came up with a hack that involves the following: Disabling text-wrapping in the textarea (plus disable padding) Checking if the textarea's scrollWidth is greater than it's width .

I create my PDF with the following code: Document document = new Document(PageSize.LETTER, 0, 0, 0, 0); PdfWriter writer = PdfWriter.getInstance(document, fileOutput); document.open(); document.add(new Paragraph(
