Win32: Unable to set Bitmap to Button
(1 answer)
Closed 7 years ago.
How do I set an image to a button in a new dialog box(DialogBox2) which opens after clicking a button in a dialog box(DialogBox1)
case WM_INITDIALOG:
hA1 = GetDlgItem(hDlg, IDD_SCORPIO);
hbitmap=LoadImage(GetModuleHandle(NULL),MAKEINTRESOURCE(IMG_BITMAPAries),IMAGE_BITMAP,0, 0, LR_DEFAULTCOLOR);
if(hbitmap==NULL)
MessageBox(hDlg,"load fail","Load",MB_OK);
else
MessageBox(hDlg,"load pass","Load",MB_OK);
if(SendMessage(hA1,BM_SETIMAGE,IMAGE_BITMAP,(LPARAM)hbitmap))
MessageBox(hDlg,"set pass","Set Image",MB_OK);
else
MessageBox(hDlg,"set fail","Set Image",MB_OK);
the bitmap loads but I am unable to set the image.
Set BS_BITMAP style for your button.

In the above imange the background window is the main window of the screen. Then follows one Form that opens from the menu of the Main Window
and at the top you can see a QMessageBox like this:
box = QMessageBox()
box.setIcon(QMessageBox.Question)
box.setWindowTitle('Αποθήκευση αλλαγών')
box.setText('Θέλετε να αποθηκεύσετε τις αλλαγές σας;')
box.setStandardButtons(QMessageBox.Yes|QMessageBox.No|QMessageBox.Cancel)
buttonY = box.button(QMessageBox.Yes)
buttonY.setText('Ναι')
buttonN = box.button(QMessageBox.No)
buttonN.setText('Οχι')
buttonC = box.button(QMessageBox.Cancel)
buttonC.setText('Ακύρωση')
box.exec_()
if box.clickedButton() == buttonY:
self.save_and_close(True)
self.main_self.manage_microphone_window_is_open = False
event.accept()
elif box.clickedButton() == buttonN:
self.main_self.manage_microphone_window_is_open = False
event.accept()
elif box.clickedButton() == buttonC:
event.ignore()
I want in the bottom the Windows (bottom bottom there that start menu of windows and clock are) to show only one program.
Any ideas?
With the help of musicmante i did the following:
I change Form Window to QDialog and set MainWindow as parent
I set a parent to box: box = QMessageBox(dlg)
Note than in step 1 when you copy paste the QWidgets from Form to new Dialog (in QtDesigner), you may change the title of window the icon of window the style of the window and perhaps any other window settings.
I'm creating a small non-modal dialog in TornadoFX like this:
find<Grib>(scope).apply { openModal(block = true,
owner = FX.primaryStage,
stageStyle = StageStyle.UTILITY,
modality = Modality.NONE) }
How do I go about setting (and retrieving) it's window position for later? That is, I have a preferences object for the window location and I want to update it so that the next time the user opens the window, it opens in the same place they last closed it.
I was able to mostly solve my problem by digging through some of the TornadoFX source code.
I added this to my init{} function:
Platform.runLater {
root.scene.window.x = Main.preferences.getDouble(GRIB_WINDOW_X, 400.0)
root.scene.window.y = Main.preferences.getDouble(GRIB_WINDOW_Y, 400.0)
}
And then adding this to my close() function:
Main.preferences.putDouble(GRIB_WINDOW_X, root.scene.window.x)
Main.preferences.putDouble(GRIB_WINDOW_Y, root.scene.window.y)
This "mostly" solves the problem in that it does save/restore the window position, however the window flickers when it is created as it moves from some default position to the newly set position.
I have created a Slider Control and an Edit Control that are linked, so that moving the slider changes the edit box's text, and manually editing the text moves the slider. For the most part it works but after I release the mouse button when dragging the Slider, the Edit Control shows 0. While I'm dragging it does show the correct value.
I can partially fix the problem by adding an if(nPos != 0) clause, which stops that happening. However when I click to move the Slider rather than drag, the Edit Control doesn't update.
Do I need a different handler for when the Slider is clicked rather than dragged? Or am I doing something wrong?
// Updates slider when value is changed in the Edit Box
void CProject1Dlg::OnChangeEdit1() {
SLIDER_1.SetPos(GetDlgItemInt(IDC_EDIT1) / 1000);
}
// Slider horizontal scroll handler
void CProject1Dlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
if (nPos != 0) {
SetDlgItemInt(IDC_EDIT1, nPos * 1000);
}
CDialogEx::OnHScroll(nSBCode, nPos, pScrollBar);
}
What happens if you try extracting the position of the slider directly with GetPos rather than using the nPos parameter?
I have such menu situation:
int menu_create(Ihandle *menu)
{
hamburger = IupItem("&Hamburger", "hamburger");
IupSetAttributes(hamburger, "AUTOTOGGLE=YES, RADIO=YES");
char* ce = "Ćev&apčići";
cevapcici = IupItem(utf8_to_cp1250(ce), "cevapcici");
IupSetAttributes(cevapcici, "AUTOTOGGLE=YES, RADIO=YES");
exit = IupItem("Exit\tAlt+F4", "exit");
img4 = IupLoadImage("icons\\delete_16x16.ico");
IupSetAttributeHandle(exit, "TITLEIMAGE", img4);
menu = IupMenu(
IupSubmenu("File",
IupMenu(
hamburger,
cevapcici,
IupSeparator(),
IupItem("Carro&t", "carrot"),
IupSeparator(),
exit,
NULL)),
NULL);
IupSetFunction("exit", (Icallback)mnu_exit);
... etc...
IupSetHandle("menu", menu);
return IUP_DEFAULT;
}
How to get "radio toggle group" functionality with items hamburger and cevapcici so first turns off a second checkmark and opposite. This is my try but it don't work.
2) I try webbrowser example from IUP suite on my windows 7. Problem is that bad black flickering appear's during resize (increase). Also, background of webbrowser flicker black during showing.
I try a same example on Ubuntu and there flickering appear's too but it is not so much visible since background is there white.
Is here any way to get rid of those flickering or if not to get white background of webbrowser window on windows?
3) Since webbrowser is ole object (on windows) is it possible to use say "print preview" or "zoom" function by reference from IUP handle or at any other way like we used to do from MS programming tools?
wbInstance.ExecWB(Exec.OLECMDID_OPTICAL_ZOOM, ExecOpt.OLECMDEXECOPT_DONTPROMPTUSER, 150, DBNull.Value)
4) How can I get key_up event fired from IupTree?
5) Interesting situation with IupTabs:
frame3 = IupHbox(mat, val, NULL);
vboxt1 = IupVbox(frame3, NULL);
vboxt2 = IupVbox(frame3, NULL);
IupSetAttribute(vboxt1, "TABTITLE", "First documents... ");
IupSetAttribute(vboxt2, "TABTITLE", "Second documents... ");
tabs = IupTabs(vboxt1, vboxt2, NULL);
hbox1 = IupHbox(tabs, IupVbox(frame, tree, frame2, NULL), NULL);
dlg = IupDialog(hbox1);
When I set frame3 which should be a same for both tabs my GUI frozes.
However, I have to got same "mat" (IupMatrix) in both tabs because by changing tabs other data load in matrix but similar enough to use same matrix and related functions.
What to do here?
1) The RADIO attribute belongs to the IupMenu, not to the IupItem. This also means that all the IupItems inside that menu will be part of the radio.
A workaround would be to manually unset the other toggle inside the action callback.
2) That flicker is not caused by IUP. Don't know why the native controls are doing it.
3) Yes, but you will have to program that using the OLE API. If you take a look at the IupOleControl and IupWebBrower source code and send me the code to do it, I will be happy to add it to IUP.
4) You don't. Use the K_ANY callbacks.
5) You can not reuse a control in different places in any dialog. So you must have two different frames, with two different matrices. What you can do is to encapsulate your matrix, so the same function will create a matrix with the same attributes and callbacks any time you want one.
I use a script which opens the story editor like this:
app.menuActions.itemByID(119793).invoke();
How can I close it programmatically? How can I detect whether it's opened or closed?
A story editor window may be closed with its close method.
Here is a function which closes the story editor window if it's open. It tests for the presence of a zoom property on the window to determine whether the window is a story editor or not (Thanks Loic Aigon for this idea)... There must be a better way of doing this but I haven't found it.
function closeStoryEditor() {
var windows = app.activeDocument.windows,
nbWindows = windows.length,
i,
closedWindow = false;
for (i = 0; !closedWindow && i < nbWindows; i += 1) {
if (!windows[i].hasOwnProperty("zoom")) {
// Let us presume that a window without a zoom method is a story editor window...
windows[i].close();
closedWindow = true;
}
}
}
To close it, it's…the same call ! if you want to check if the editor is already opened, you can loop through all open windows like this :
app.activeDocument.windows.everyItem().name;
and see for matches.
