I have an QHBoxLayout that includes two QLabel Widgets. My left QLabel is much larger than my right QLabel, however, the QHBoxLayout is splitting the output in half, so the left side of the layout is too small and the right side of the layout is too big. How do I modify the QHBoxLayout to create unequal proportioned space for each included widget?
View 1 RepliesI have QTextEdit in mainWindow. I'm trying to resize QTextEdit so height = mainwindow.height and width = height/2. That should change when I change the size of mainWindow during runtime. How can I do that?
View 2 Replies View RelatedI need to write a widget that will implement some matrix functions using data from a text file. The input data will be spreadsheet like and fully determined with complete rows and columns. I need to do the following,
1. populate a data structure with the input data (double) to create matrix x
2. transpose the input data matrix x to create x'
3. multiply x * x' to create a square matrix x'x
4. take the determinant of x'x
This is pretty standard linear algebra, but not something I have done in cpp before. Implementation such as the best data types to use to store each of the three matrices, how they are sized, and what library functions may be available for the matrix functions like transpose, multiply, determinant, etc.
I will be removing each data row from the initial input to observe the effect on the determinant in case that has any effect on program design.
I have an MDI MFC application which has a menu at the top. Nothing particularly unusual about that, but for some reason my application seems to have a vertical spacing about 30%-40% bigger than "normal" on the drop down menus (when compared with Visual Studio itself).
I've looked thru the options for CMenu, CMFCMenuBar, CMFCVisualManager, but can't seem to find anything to explain why my menu has such a large vertical spacing between options, nor how to change it.
So I have to write a program that outputs a check with correct spacing and everything.
Create a project titled Lab7_Check. Write a program that asks the user the check information and prints the check. The dialog should be as follows:
date: 2/23/2010
name: William Schmidt
amount, dollars: 23
cents: 30
payee: Office Max
your check:
William Schmidt 10/13/2013
pay to: Office Max $23.30
twenty three and 30/100 dollars
You may assume that a person always has the first name and last name (no middle names or initials). The payee name is also always two words. The dollar and cent amount are integers and the amount is always less than 100 dollars. Note that the dollar amount could be zero, in which case, when you spell the dollar amount, it should print "zero". The date is always a single (non-white space separated string). Your date, dollar amount in numbers and the word "dollars" have to vertically align.
This is the code I have so far.
#include <iostream>
#include <string>
using namespace std;
int main(){
string date;
string firstname;
string lastname;
[Code] .....
I have a char *pch that points to an integer digit 1 or 2 or ... 9. To get the character that's 1 less, instead of converting to int, minus 1, then converting back to char, I tried (*pch -1) and that seemed to work. I suppose that's because the particular character encoding on my system is such that the digits are encoded in the same order and spacing as the integers they represent. So the question is does this "convenience" feature hold true for all character encoding systems?
