I try to set text of Text element in my stimulsoft report via code.I use this code in TextEditor windows into Expression tab.but don't work .I try to use this code into BeforPrintElement and AfterPrintElement events but in this case don't print any things.
How to fix this?
{if(ProcGetReportTRAINPDF.Fk_sellerCode=="8006")
{
AgencyCommission.value= ((int.Parse(ProcGetReportTRAINPDF.Formula10)*2)/100).Tostring();
}
if(ProcGetReportTRAINPDF.Fk_sellerCode=="8025")
{
AgencyCommission.value= ((int.Parse(ProcGetReportTRAINPDF.Formula10)*1.8)/100).Tostring();
}
}
The Value of the text component is compiled as a method, so it's impossible to change text this way.
You should use the GetValue event of the text component.

I have a desktop program with a WinRT/C++ library (and Microsoft.UI.Xaml.Controls 2.8 prerelease), which in the application will bring up a ContentDialog with a TextBox as its content. However, unfortunately the TextBox does not accept any character input from the keyboard, even though the TextBox is in a focused state. For the experiment so far, the TextBox can only accept input from the Copy and Paste methods. So, is there any workaround or manipulation that can be done to solve this problem?
Code:
TextBox tbox{};
ContentDialog dialog{};
dialog.Title(box_value(L"Title"));
dialog.Content(tbox);
dialog.PrimaryButtonText(L"Create");
dialog.CloseButtonText(L"Cancel");
dialog.XamlRoot(XamlRoot());
auto result = co_await dialog.ShowAsync();
if (result == ContentDialogResult::Primary)
{
// Create new data from tbox.Text()
}
My first approach to the problem was to call the GetWindowsText method on the CComboBoxEx control, but I found that there is no associated text. After analyzing the control with Spy++ and reading some documentation on CComboBoxEx, I realised that these type of controls are only the parent of a classic ComboBox:
I tried using the GetLBText() method on the child ComboBox, passing GetCurSel() as an argument, but I only get some wrong text (the correct text should be "English"):
Am I missing something? Thanks in advance!
What you want to do is map the control to a int variable using Class Wizard:
Now it is easy to access the selected text at any time. You need to use the GetItem function. For example (code not tested):
COMBOBOXEXITEM cmbItem;
CString strText;
cmbItem.mask = CBEIF_TEXT;
cmbItem.iItem = m_cbItemIndex;
cmbItem.pszText = strText.GetBuffer(_MAX_PATH);
m_cbMyCombo.GetItem(&cmbItem);
strText.ReleaseBuffer();
In short, you need to use the COMBOBOXEXITEM and initialise it with the right flags to state what information you want to get from the extended combo. That, and the item index. Job done!
I realise that you have your own inherited class, but the mechanics are the same. You don't use GetLBText. You use the structure with the index and GetItem to get the selected text.
In the end I managed to retrieve the correct name; as you can see in the image below, the ComboBox is only a child of a CombBoxEx32:
I retrieved the pointer to the parent ComboBoxEx32 from the child ComboBox, and searched for the text this way:
CString szText;
CComboBoxEx cbParentCombo ;
cbParentCombo.Attach( GetParent()->GetSafeHwnd()) ;
cbParentCombo.GetLBText( GetCurSel(), szText) ;
cbParentCombo.Detach() ;
My mistake was that I was calling GetLBText() directly from the child ComboBox, instead of the parent CComboBoxEx; because of that, all I was getting was some random gibberish. GetLBText() was indeed the correct solution.
QTextEdit can be appended text to simply using append(). However, if the document is rich text, every time you append to the document, it is apparently reparsed. This seems like a bit of a trap in Qt.
If you're using the edit box as a log window and appending text in fast successions as a result of external signals, the appending can easily hang your app with no intermediate appends shown until each of the appends have completed.
How do I append rich text to a QTextEdit without it slowing down the entire UI?
If you want each append to actually show quickly & separately (instead of waiting until they've all been appended before they are shown), you need to access the internal QTextDocument:
void fastAppend(QString message,QTextEdit *editWidget)
{
const bool atBottom = editWidget->verticalScrollBar()->value() == editWidget->verticalScrollBar()->maximum();
QTextDocument* doc = editWidget->document();
QTextCursor cursor(doc);
cursor.movePosition(QTextCursor::End);
cursor.beginEditBlock();
cursor.insertBlock();
cursor.insertHtml(message);
cursor.endEditBlock();
//scroll scrollarea to bottom if it was at bottom when we started
//(we don't want to force scrolling to bottom if user is looking at a
//higher position)
if (atBottom) {
scrollLogToBottom(editWidget);
}
}
void scrollLogToBottom(QTextEdit *editWidget)
{
QScrollBar* bar = editWidget->verticalScrollBar();
bar->setValue(bar->maximum());
}
The scrolling to bottom is optional, but in logging use it's a reasonable default for UI behaviour.
Also, if your app is doing lots of other processing at the same time, appending this at the end of fastAppend, will prioritize actually getting the message displayed asap:
//show the message in output right away by triggering event loop
QCoreApplication::processEvents();
This actually seems a kind of trap in Qt. I would know why there isn't a fastAppend method directly in QTextEdit? Or are there caveats to this solution?
(My company actually paid KDAB for this advice, but this seems so silly that I thought this should be more common knowledge.)
Ive made a search function for my List Control in Report View in my MFC Dialog. It looks like this
m_List.SetItemState((m_List.FindItem(&Finde)),LVIS_SELECTED,LVIS_SELECTED );
It searches the Content that is in the Variable Finde and marks it. Now it should mark the row. But I first have to click somewhere in the program. It doesnt mark the row directly after the function gets called.
Can anyone help me?
Here is the full function
LVFINDINFO Finde;
Finde.flags = LVFI_PARTIAL|LVFI_STRING;
Finde.psz = _T("Siffert");
if ((m_List.FindItem(&Finde)) != -1)
{
m_List.SetItemState((m_List.FindItem(&Finde)),LVIS_SELECTED,LVIS_SELECTED );
//m_List.SetSelectionMark((m_List.FindItem(&Finde)));
}
else
{
MessageBox(_T("No Results"));
}
You need to use the style LVS_SHOWSELALWAYS
Otheriwse the selection is only shown when the control has the focus and is active.
EDIT: Also keep in mind that there is also a LVIS_FOCUSED style, that also forces scrolling to this item.
So I'm making a text editor using Qt and right now I have a button that opens a dialog called "Format text". I want it to work kind of like the dialog in notepad called "font" where you select a few text attributes from some drop down lists and it shows you what your text will look like. Right now I have it working where you can select the font style, font color, and font size and hit preview and it shows you in a box in the dialog what your text will look like. However, I have a button called "okay" which is supposed to change the highlighted text or the text you are about to type, but I can't figure out how to display those changes on the main window. The .ui files are private and a lot of the already made functions and pointers are the same in every ui file so if I change the ui file to pubic I have to change a whole bunch of things. Can anyway give me a simple answer? I'm trying to do this with as little confusion as possible. More coding and less confusion is better than less coding and more confusion for someone of my skill level. Sorry that this is all one giant paragraph and that I didn't provide any code, but I didn't think the code was necessary, however if you do need some of the code i'd be happy to share it.
Thank you for your help and your time. I hope you all have a nice evening.
QDialog have a signal called finished(), you can connect this signal with your slot. To accomplish your work, pass a QSettings or for simplicity QStringList to dialog settings (responsible for changing font, color ...), the QStringList will save user defined settings, after closing the dialog, iterate through QStringList member to alert Main window.
A pseudo code will look like this
Class Editor:
Editor::Editor()
{
TextSettings textSettings;
textSettings.setSettings(settings); // settings is a member
connect(textSettings, &finished(int)), this, SLOT(alertEditor(int)))
}
Editor::alertEditor(int s)
{
if(s == 0)
{
for (int i = 0; i < settings.size(); ++i)
settings.at(i).toLocal8Bit().constData(); // extract various user settings
}
}
Class TextSettings:
TextSettings::TextSettings(QStringList settings)
{
settings << ui->combobox->currentItem(); // font name as example
}
