is it possible to embed WxWidgets Controls in a MFC based application?
In detail, is there a way to use wxWidget Controls inside a MFC Control? specially CView, CFormView or CDockablePane?
I have a huge MFC appication with rich GUI features.
I need to extend this application with a feature, that user will be able to display application data by creating his own views.
I could start this task with an approach like this: XUIFramework: A GUI Framework based on XML and MFC[^]
Actually it would work with some simple MFC controls, but there will be a lot of work to make it more functional.
So my basic idea is, to use wxWidgets because of its rich functionality. But I cannot rewrite the complete application to base it on wxWidgets instead of MFC.
An further advantage of wxWidget would be, that it should be very easy to create a runtime for other systems like linux to run the user's GUI!
I have found in internet a few comments about such an approach. some says, it could be possible. But I have not found anything concrete. If I would have a very basic sample, I could start such a project.
is it anyhow possible to mix or overlay MFC Controls in OpenGL controlled screen area?
My aim is as follows:
I have 3D animation (like industrial robot visualisation). Nearby 3D objects I want to display object related information (e.g. with a CListBox Control).
I have already a lot of Controls, based on MFC Controls with enhanced functionality. I want to reuse this at top of a 3D scene?
Any ideas, if it is possible or how I should start?
Write a simple expression evaluator that takes a string like the following as input: 1+2*(3+4).
-Only integers need to be supported
-The following operators should be supported: +, -, *.
-Expressions within parenthesis should be evaluated first.
-Then the resulting expressions should be evaluated from left to right (no operator precedence)
4+(4-(2*3)+1)+4 = 7
The code should be written in such a way to support additional operators.
Assume the existence of a function tokenise, which could take a string and return an array of strings, for instance
tokenise(‘1+(2*3)+4’) would return [‘1’,’+’,’(‘,’2’,’*’,’3’,’)’,’+’,’4’]
and the functions isNumber and asNumber which would return a Boolean and integer respectively on a single string input.
We do not do exam questions here. You see, Like it or not, whether you get your degree or diploma, or not, the real test is: 'Can you do the Job.' Degrees and diploma's are there to sort the corn from the chaff. I Myself have no degree in Computer Science, for the simple reason that in the 1970's when I went to university, computers where things that only large government institutions could afford, the cost of each of them involved billions, and no one was allowing students access to expensive things like that. I studied pure mathematics instead. You are damn lucky that you have access to an affordable computer, with a power that is a large number of magnitudes greater than the machines costing billions some 40 odd years ago!
What happened? Did you miss a Semester at College, or what? Also, Is this an exercise in What? It could de C or CPP (My Guess)
Or, if it is MFC, did you write the Interface, and are now stuck for 'Where the Rubber meets the Road'
For you, and, Only for Once, just a bit of a leg up, to do my bit for humanity.
I Suggest you start searching for 'Reverse Polish Notation' (RPN) to at least get you started.
As a Further bit of help, the question does not ask you do the harder part, (writing the Tokeniser)you only have to write code to evaluate it's result. Should not take too much effort.
On pain of being blackballed by fellow members, I remark that you are requested to implement an abstract RPN execution stack.
