I have a dialog that I want to place within another dialog and position relative to one of the controls on the main dialog.
void CspAceDlg::DrawResultsArea()
{
CWnd* pTabCtl = GetDlgItem(IDC_BUILDTABS);
CRect rectTabCtl; // Allocate CRect for control's position.
pTabCtl->GetWindowRect(&rectTabCtl);
int resX = rectTabCtl.right + 15;
int resY = rectTabCtl.top;
//RESULTS AREA
results.Create(IDD_RESULTSDIALOG, this);
results.SetWindowPos(this, resX, resY, /*608, 19, */175, 135, SWP_SHOWWINDOW);
results.ShowWindow(SW_SHOW);
}
My problem is that my dialog resource (IDD_REULTSDIALOG) has properties called X Pos and Y Pos that seem to be overriding my SetWindowPos() (and the little property tab in the resource editor won't let me leave these blank). If I set these properties to 0, 0 my dialog appears in the top left corner of the main dialog. If I set them to a number I can guess-and-test place it roughly where I want, but then running the application on different resolutions causes the dialog to appear in different spots. What I really want to do anyway is place the dialog relative to another control on my main dialog (in this case my tab control). Why is my SetWindowPos() being ignored, and how do I fix this? Should I be using a different function?
According to the documentation for SetWindowPos, if you pass in SWP_SHOWWINDOW, the window will not be moved:
If the SWP_SHOWWINDOW or SWP_HIDEWINDOW flag is set, the window cannot be moved or sized.
Figured it out myself, largely due to this thread.
My code came out looking like this:
void CspAceDlg::DrawResultsArea()
{
CRect rectTabCtl; // CRect representing tab control's position.
POINT pResXY;
POINT pResWH;
CWnd* pTabCtl = GetDlgItem(IDC_BUILDTABS);
pTabCtl->GetWindowRect(&rectTabCtl);
pResXY.x = rectTabCtl.right + 15;
pResXY.y = rectTabCtl.top;
pResWH.x = pResXY.x + 175;
pResWH.y = pResXY.y + 135;
ScreenToClient(&pResXY);
ScreenToClient(&pResWH);
//RESULTS AREA
results.Create(IDD_RESULTSDIALOG, this);
//results.SetWindowPos(this, resX, resY, /*608, 19, */175, 135, SWP_SHOWWINDOW);
results.MoveWindow(pResXY.x, pResXY.y, pResWH.x, pResWH.y, TRUE);
results.ShowWindow(SW_SHOW);
}
What fixed this problem for me, was setting the program's compatibility properties to "run this program as an administrator".

I want to add close button to top right corner of a dialog box.
I tried using setbounds with addactor and just add and setposition with setsize and addactor, but nothing works. I know that dialog works with table layout, it has a table for content and for buttons. I don't want to use this layout and put the button outside this layout like on the border of the dialog.
How can I do it?
This is how it should be:
The easiest solution I could come up with now, is to use negative padding for your button to move it "outside" of it's cell.
Button closeButton = new TextButton("X", skin, "default");
getTitleTable().add(closeButton).size(60, 40).padRight(-30).padTop(-20);
With this padding hack you have the problem, that the button will be outside of your Dialog, and by default, Window checks the bounds of your window when it performs Actor.hit(...) evaluation.
We need to disable clipping for that reason, but the rendering of the window depends on it. That's why we use another hack to enable it, just for the rendering:
#Override
public void draw(Batch batch, float parentAlpha) {
setClip(true);
super.draw(batch, parentAlpha);
setClip(false);
}
Do this:
private Stage stage;
private Window window;
private Table table;
#Override
public void show() {
table = new Table();
table.setSize(Gdx.graphics.getWidth() / 2
, Gdx.graphics.getHeight() / 5);
window = new Window("", skin);
window.setSize(table.getWidth(), table.getHeight());
Button btnWindow = new Button(skin, "close");
btnWindow.addListener(new ClickListener() {
#Override
public void clicked(InputEvent event, float x, float y) {
window.setVisible(false);
}
});
window.addActor(btnWindow);
btnWindow.setSize(50, 50);
btnWindow.setPosition(window.getWidth() - btnWindow.getWidth()
, window.getHeight() - btnWindow.getHeight());
table.addActor(window);
window.setModal(true);
table.setPosition(Gdx.graphics.getWidth() / 2 - window.getWidth() / 2
, Gdx.graphics.getHeight() / 2 - window.getHeight() / 2 +
100);
window.addAction(Actions.sequence(Actions.alpha(0)
, Actions.fadeIn(.1f)
, Actions.moveTo(+50, +50, 1)));
stage.addActor(table);
}
I had a similar problem. After a bit of searching this thread helped me.
Basically to tell the alignment of the actors inside a table, and to tell the alignment of the table itself are two separate things. Setting the alignment of the table top top-left would produce the desired behavior.
table = new Table();
table.setFillParent(true);
table.setSkin(usedSkin);
table.setDebug(true);
table.top().left();
stage.addActor(table);
table.add(exitBtn);
I'm a little new to using MFC and VC++ as such, but I'm doing this as part of a Course and i Have to stick to VC++.
http://www.cprogramming.com/tutorial/game_programming/same_game_part1.html
This is the tutorial I have been following to make a simple samegame. However when i try to display score, the score is getting displayed Underneath or outside my application window, even though I've displayed score before calling updateWindow(). I've tried various methods but I am kinda lost here.
Here is the code I'm using to Display the score:
void CSameGameView::updateScore()
{
CSameGameDoc* pDoc = GetDocument();
CRect rcClient, rcWindow;
GetClientRect(&rcClient);
GetParentFrame()->GetWindowRect(&rcWindow);
int nHeightDiff = rcWindow.Height() - rcClient.Height();
rcScore.top=rcWindow.top + pDoc->GetHeight() * pDoc->GetRows() + nHeightDiff;
rcScore.left=rcWindow.left + 50;
rcScore.right=rcWindow.left + pDoc->GetWidth() - 50;
rcScore.bottom=rcScore.top + 20;
CString str;
double points = Score::getScore();
str.Format(_T("Score: %0.2f"), points);
HDC hDC=CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL);
COLORREF clr = pDoc->GetBoardSpace(-1, -1); //this return background colour
pDC->FillSolidRect(&rcScore, clr);
DrawText(hDC, (LPCTSTR) str, -1, (LPRECT) &rcScore, DT_CENTER);
}
Thank you for any help and I'm sorry if the question doesn't make sense or in ambiguous.
There are several problems with your code:
1. The hDC you are creating is going to have coordinates relative to the desktop window. To paint text in your window, use CClientDC like this: CClientDC dc(this); (see http://msdn.microsoft.com/en-US/library/s8kx4w44%28v=vs.80%29.aspx)
2. The code you have will leak a DC every time the function is called. The method in #1 will fix that.
3. Your paint code should be done in the CView::OnDraw. There you get a DC passed to you and you don't have to worry about creating one with CClientDC. Set the variables you want to draw (e.g. your points or score), store them as class members and draw them in CView::OnDraw.
Don't do the drawing in your updateScore method.
Make sense? Hang in there!
In MFC how to remove a menu-item of POPUP type. RemoveMenu() either take ID or position. Since, there is no ID for POPUP menu, option left is by using position.
But I am not getting how and where I can call RemoveMenu().
File Edit Test
Test_submenu_1
Test_submenu_2
Test_submenu_3 > submenu_3_item_1
Test_submenu_4
Test_submenu_5
I want to remove Test_submenu_3? I am not getting how do find CMenu object for Test so that I can call RemoveMenu() by passing position "2" for submenu_3_item_1.
Any suggestion for doing this will be greatly appreciated.
Thanks!
You cannot use LoadMenu, since this function does just that.
After modifying loaded menu it is killed when menu object used to load it goes out of scope. You have to modify menu that is currently used.
Your menu is a popup part of the main menu, second in position. It contains 5 items and second one is another popup. To my understanding, you want to remove this item and popup of this item.
To make it work you will have to ask main window for the current menu:
CMenu* pMenu = GetMenu(); // get the main menu
CMenu* pPopupMenu = pMenu->GetSubMenu(2);//(Test menu with item....)
pPopupMenu->RemoveMenu(2, MF_BYPOSITION);
Of course, this code is from the main frame. If you want to use it elsewhere, you will have to access all using pointer to the main frame.
Try the below. You get the Test sub-menu first (index 2), then once you have that you tell it to remove its Test_submenu_3 submenu by position (also 2).
CMenu topMenu;
topMenu.LoadMenu(IDR_YOUR_MENU);
CMenu& testSubMenu = *topMenu.GetSubMenu(2);
testSubMenu.RemoveMenu(2,MF_BYPOSITION);
'Test' is the 3rd menu item (by position) on the top level menu. It's just been rendered horizontally rather than vertically. Assuming you have a handle to the top level menu use the same code you'd use to the get the sub menus as you would to get the 'Test' menu.
You can use this below code to remove the submenu, by comparing name
bool RemoveSubmenu(CMenu * pMenu) {
for (int pos = 0; pos < pMenu->GetMenuItemCount(); pos++) {
wchar_t *name = new wchar_t[mf.cch + 1];
MENUITEMINFO mf;
ZeroMemory(&mf, sizeof(mf));
mf.cbSize = sizeof(mf);
mf.fMask = MIIM_SUBMENU | MIIM_FTYPE | MIIM_STRING;
mf.fType = MIIM_STRING;
mf.dwTypeData = NULL;
if (!GetMenuItemInfo(pMenu->m_hMenu, pos, TRUE, &mf))
break;
if (mf.hSubMenu != NULL){
mf.fMask = MIIM_TYPE;
mf.fType = MFT_STRING;
++mf.cch;
mf.dwTypeData = (LPSTR)name;
if (!GetMenuItemInfo(pMenu->m_hMenu, pos, TRUE, &mf)){
bRet = false;
break;
}
//
// compare sub menu name (i.e mf.dwTypeData) here, do the required
// modifications
//
pMenu->RemoveMenu(pos, MF_BYPOSITION);
bRet = true;
break;
}
}
}
I have a FlowLayoutPanel and a UserControl.
I've added multiple usercontrols into the FlowLayoutPanel, and I'm trying to dock them to the top, so when I change the size of the FlowLayoutPanel the size (width) of the usercontrols changes accordingly.
You cannot dock anything inside a FlowLayoutPanel, it's simply ignored.
Check out the answer here apparently posted by the Microsoft team.
They say:
The FlowLayoutPanel relies on a largest control to effectively define the column/row within it. The code below set's the size of the first control to the width of the FLP to achieve a layout similar to what you want.
private void flowLayoutPanel1_Layout(object sender, LayoutEventArgs e)
{
flowLayoutPanel1.Controls[0].Dock = DockStyle.None;
for (int i = 1; i < flowLayoutPanel1.Controls.Count; i++)
{
flowLayoutPanel1.Controls[i].Dock = DockStyle.Top;
}
flowLayoutPanel1.Controls[0].Width = flowLayoutPanel1.DisplayRectangle.Width - flowLayoutPanel1.Controls[0].Margin.Horizontal;
}
Key thing is to use the Layout event.
This solution worked for me up to a point. Your UserControls have to have AutoSize turned off / stay a uniform size.
In my case I wanted AutoSize turned on so as to allow the UserControl to expand/contract vertically while filling the width of the FlowLayoutPanel.
I had to find a different solution. But the above might help you in your case.
I have a resizeable CListCtrl and I want to avoid any item being displayed partially, ever.
For example:
I want Item 9 to not be displayed in this case. Is there a flag or method for this? How would you go about solving this issue?
I tried the following and it was no good:
void CMyCListCtrl::OnEndScrolling()
{
int iCount = this->GetCountPerPage();
EnsureVisible(iCount - 1, FALSE);
}
after catching
...
ON_NOTIFY( LVN_ENDSCROLL, IDC_LIST1, OnEndScroll )
...
void CWheelTestDlg::OnEndScroll(NMHDR* pNMHDR, LRESULT* pResult)
{
LPNMLVSCROLL pnmLVScroll = (LPNMLVSCROLL) pNMHDR;
m_MyListCtrl.OnEndScrolling();
*pResult = 0;
}
In the CListCtrl parent dialog. (which I don't want to do, I want to do everything in my CListCtrl derived class only, if possible).
All I accomplish is showing item 9 completely, but item 10 is partially visible below it. If I have 30 items I don't want to scroll the list to show item 30, I want to show up to item 8 with no partially visible item below it.
CListCtrl doesn't appear to support Integral Height.
Here's a solution that accomplishes what you desire by forcefully changing the control height [with commented conditions] (http://www.codeproject.com/Messages/418084/Socket-accept-call.aspx):
/////////////////////////////////////////////////////////////////////////////////
// This assumes a REPORT-style CListCtrl.
//
// Resize the control. This works correctly only if scrolling is disabled. If
// there is scrolling, then setting to the size from ApproximateViewRect() will
// always give scroll bars showing. Which is irritating.
//
// We need to adjust the vertical size from what ApproximateViewRect() returns
// by one row minus border width
//////////////////////////////////////////////////////////////////////////////////
CSize sz = m_list.ApproximateViewRect(); // always adds room for a new row
CRect itRect; // Get the height of a single row (there had better *be* a row!)
m_list.GetItemRect(0, &itRect, LVIR_BOUNDS);
int vOffset = itRect.Height() - 3; // leave a little 'cuz it looks better
m_list.SetWindowPos(NULL, 0, 0, sz.cx, sz.cy - vOffset,
SWP_NOZORDER|SWP_NOACTIVATE|SWP_NOMOVE);
I have the similar problem in wince, and find a solution accidentally. No direct solution in internet, so i decide to re-position scroll bar after receive some message, and the only message i can used in wince is WM_LBUTTONDOWN, other messages such as OnEndScroll are not called, maybe something wrong in my code.
Whatever, i use Timer（ON_WM_TIMER） to re-position scroll bar when receive WM_LBUTTONDOWN message, then find that list control doesn't scroll automatically! then i remain a empty OnTimer function and remove everything else. It works, and i guess list control use Timer to scroll partial row.
Hope useful to you.
