如何在monomac中打印?这就是我所能得到的,但是我似乎不能在NSView中获得对图形上下文的引用。如果我将一个控件添加到PrintDoc中,这很好,但我想要绘制。
//Print Function
void Print(){
PrintDoc NewDoc = new PrintDoc ();
NewDoc.SetFrameSize(new SizeF(600,1000));
NSPrintOperation P = NSPrintOperation.FromView (NewDoc);
P.RunOperation ();
}
//NSView to b
我正在尝试打印一个简单的NSString值。但它给了我一个对话,说:
"Printing Now Allowed
This application is not allowed to print.
Please contact your application vendor for an update."
我使用的代码是:
-(void)printText:(NSString*)text
{
NSTextView *printView = [[NSTextView alloc] initWithFrame:NSMakeRect(0, 0, 468, 648)];
#include <bits/stdc++.h>
using namespace std;
int freq[101034];
int main() {
int n;
cin >> n;
set<int> st;
for (int i = 0; i < n; i++) {
int x;
cin >> x;
freq[x]++;
st.insert(x);
}
while (!st.empty()) {
for (auto x : st) {
if (freq[x
当插入到map中时,我无法捕获分配内存的失败,这会由于分段错误而导致崩溃。
struct Data
{
int64_t arr[100000000000000000]; // Large data to cause allocation failure
};
typedef unordered_map<int64_t, Data> UOM;
int main()
{
//void* p = malloc(sizeof(int64_t)*100000000000000000);
//void* p = new int64_t [10000000000000
