I have to many points on my chart so when I am clicking through on mobile or small screen my tooltip just showing data from multiple points:
I researched on that and find out the the best approach would be is to disable the tooltip on small screens. I tried to follow this advice from the docs. But have no luck:
options: {
// This chart will not respond to mousemove, etc
events: ['click']
}
Also I found that but I think it is actually related to what I just did based on the advice form the docs.
Any ideas how to fix?
Tooltips can be disabled in the options as shown below (see Tooltip Configuration):
option:
tooltips: {
enabled: false
}
...
}
Instead of using a hard coded value false, you may obtain the value from a function that returns true or false depending on the screen size.
option:
tooltips: {
enabled: window.screen.width > 400
}
...
}
I've no experience in creating web apps for mobile devices. Therefore
400 is probably not the right choice. The following answer should help
finding the appropriate function: https://stackoverflow.com/a/11381730/2358409

I have added a print preview feature to my program. The problem is, it does not display the preview document well on screen resolutions above 1920 x 1080.
Example:
Code:
QFont docFont;
docFont.setPointSize(14);
QTextDocument *textDoc = new QTextDocument(this);
textDoc->setDefaultFont(docFont);
textDoc->setPlainText(getHardwareData());
During a debugging process I have found the following issues:
QWindowsMultiFontEngine::loadEngine: CreateFontFromLOGFONT failed for "Courier": error 0x88985002 : Indicates the specified font does not exist.
QWindowsMultiFontEngine::loadEngine: CreateFontFromLOGFONT failed for "Courier": error 0x88985002 : Indicates the specified font does not exist.
Is there any hint/font to make it look well on all screens resolutions?
Edited:
I have fixed the QWindowsMultiFontEngine::loadEngine: CreateFontFromLOGFONT failed for "Courier" issue. The problem was caused by a Unicode character in Peripheral data. Now, the only thing left is to make it look better on 4K.
I have found some hack to get the toolbar actions from a print preview dialog. By adding some additional logic it fixed the issue.
QList<QToolBar*> toolbarList = printPreviewDlg->findChildren<QToolBar*>();
if (!toolbarList.isEmpty()) {
if (screenSize.width() > 1920 && screenSize.height() > 1080) {
toolbarList.first()->actions().at(0)->activate(QAction::Trigger);
} else {
toolbarList.first()->actions().at(1)->activate(QAction::Trigger);
}
}
To detect the screen size I use the native Win API methods. Now, it automatically triggers the Fit to width toolbar option and sets a better preview on 4K monitor. It works depending on the screen size. The issue is resolved.
I'm using the latest version of Chart.js and am trying to make the line chart fit run right up to the edge of the containing div but when I enable the yAxes ticks it adds a small padding to the right or in other words pushes the graph to the left.
How can I have tick labels and also have the chart extend to the edges of the <canvas />?
See screenshots:
You should be able to resolve some things like that by using the different callback hooks that are available in the update process.
Testing things out on my own, I was able get it to fix that gap by setting the right padding on the axis to 0 in the afterFit method, which based on the docs is:
Callback that runs after the scale fits to the canvas
const options = {
scales: {
xAxes: [{
afterFit: (axis) => {
axis.paddingRight = 0;
}
}]
}
}
I am using Foundations Joyride plugin in my web app. What I am trying to achieve is something like where the user can say that never show me again button on each step.
For example I am on the first item their I want two buttons, Next/Don't show again.
Is there a way to get that?
I had this issue and solved it by making a separate popup in the same style which came up to prompt the user to do something else (in this case start a video) or start the joyride.
On this we also included a checkbox called 'never show me this again' and then stored the result in a cookie to make sure the box didn't auto-popup when reloading the page.
The following code should help (you will need to set or clear the 'show_joyride' cookie yourself - we use js.cookie.js):
var showJoyride = Cookies.get('show_joyride');
// Setup joyride but tell it not to auto start
$("#joyRideTipContent").joyride({
autoStart : false,
modal:true,
expose: true
});
if(showJoyride == 'true'){
// Start the joyride
$("#joyRideTipContent").joyride({
modal:true,
expose: true
});
}
I have a problem with the FreeTextBox rich Text Editor in my ASP.NET site. The problem occurs when I access the site with firefox, and I have a freetextbox instance in a hidden div. The hidden div might also be an AJAX Tab Panel. The actual problem is that when the page loads it throws an uncaught exception (firebug shows the StoreHtml() function) and halts the postback!!
Is anywhere of the problem and a solution for it??
Thanks
I recently met a similar problem with jQuery UI tabs. What you need to do is to change the CSS for hidden tabs to something like:
.hiddentab
{
position: absolute;
left: -99999999999999;
}
This puts hidden tabs far to the left, and in absolute position mode this does not cause horizontal scroll bars to appear. When the tab is shown, simply remove the hiddentab class from the tab element.
This will work if the problem is related to Firefox' odd behavior with display: none.
I have found another solution to the problem in case anyone is looking for it. What I did was use javascript to override the OnSubmit function of the form, thus catching the exception that caused the problem and going on with the rest of the code.
However the solution is kind of "hack" since it does not cover every situation. I found the solution in the FreeTextBox forum and tried it out and it works. The only difference in my code is that I return true in the end of the override function:
function OvrdSubmit()
{
var ftbSubmit=document.forms[0].onsubmit;
if (typeof(ftbSubmit) == 'function')
{
document.forms[0].onsubmit = function()
{
try{ftbSubmit();}
catch(ex){}
}
}
// We are ok
return true;
}
Since my site is an ASP.NET site I also had to add this line in the Page_Load():
ClientScript.RegisterOnSubmitStatement(this.GetType(), String.Concat(this.ClientID, "_OnSubmit"), "javascript: return OvrdSubmit();");
Hope it helps anyone with the same problem.
Firefox has a problem with being inside anything with a style of display:none. What I did was to use a div with a zIndex that hid the div until I needed it displayed. I would start there.
Thanks for your answer, however my problem currently is that the FreeTextBox is inside an AJAX Tab Panel, therefore I would have to reconstruct the whole tab functionality in order to do so, and I do not have adequate time!
For what it's worth, I am close to a solution (I think) by setting the .ReadOnly attribute of the FTB to true and then setting it back to false on the controlo .PreRender. It works for the first time the page loads, so now I have to figure out how to implement this properly for every postback.
I will post the solution if I find it!
Thanks anyway!
I have a CMFCRibbonStatusBar in my mainframe to which I add a CMFCRibbonButtonsGroup which again has a CMFCRibbonButton. This button has the same ID as a menu entry.
Creating the button is done as follows:
CMFCRibbonButtonsGroup* pBGroup = new CMFCRibbonButtonsGroup();
CMFCToolBarImages images;
images.SetImageSize(CSize(32, 16)); // Non-square bitmaps
if(images.Load(IDB_STATUSBAR_IMAGES))
{
pBGroup->SetImages(&images, NULL, NULL);
}
m_pStatusButton = new CMFCRibbonButton(ID_STATUS_SHOWSTATUS,
_T(""),
IMAGEINDEX_DEFAULTSTATUS);
pBGroup->AddButton(m_pStatusButton);
m_wndStatusBar.AddExtendedElement(pBGroup, _T(""));
I want to use this button as a status indicator.
I want to display a tool tip in the following two cases:
when the status changes and
when the user moves the mouse over the button.
I have no idea how to start in the first place. I have looked at the ToolTipDemo and DlgToolTips sample projects but couldn't figure out how to do it since all they do is display tooltips for the toolbar items or dialog buttons (CWnd-derived instead of CMFCRibbonButton).
If you are familiar with the ToolTipDemo sample project: Since there seem to be several ways of doing things, I would prefer the tooltip to look like the "Extended Visual Manager-based" tool tip as shown in this screenshot.
Thanks!
I don't think it's possible to show the tooltip without the mouse cursor being over the control. That's all done automatically.
However if you want to have a nice looking tooltip like in your screenshot, you need to call SetToolTipText and SetDescription, like this:
CMFCRibbonButton* pBtn = new CMFCRibbonButton(12345, _T(""), 1);
pBtn->SetToolTipText("This is the bold Title");
pBtn->SetDescription("This is the not-so-bold Description");
pGroup->AddButton(pBtn);
I am using CMFCRibbonButton controls within a CMFCRibbonButtonGroup, which is added to the CMFCRibbonStatusBar. Take note of the 4th parameter in the CMFCRibbonButton() constructor, bAlwaysShowDescription, as this seems to affect the behavior depending upon whether SetDescription() has been called.
Specifically, if SetDescription() has not been called, it doesn't matter whether bAlwaysShowDescription is TRUE or FALSE - the tool tip is displayed (as I would expect). If SetDescription() is set and bAlwaysShowDescription is FALSE, when hovering over the button the tool tip is displayed with the description below it.
What seems counterintuitive given the name of this bAlwaysShowDescription parameter, is that when this is TRUE and SetDescription() is set, NEITHER the tool tip nor the description appear. I wonder if this is related to this post:
https://connect.microsoft.com/VisualStudio/feedback/details/399646/cmfcribbonbutton-wont-show-tooltip-if-balwaysshowdescription-1
Hope this helps and you can achieve what you need with the different combinations of bAlwaysShowDescription parameter and whether SetDescription() is set.
